"As a project engineer and program manager for 35 years, I have used curve-fitting programs
throughout my career, but this one is lightweight and yet more powerful than anything on the market.
EasyFit used with Excel is not only fast and simple but also gives me a quick feel for best fit among
tried-and-true distributions. The new distributions in their database offer knowledge which I am still
learning about. By the way, I developed conclusions faster than our statistics group, which were verified
by them weeks later."
David G. Beshore, Senior Project Engineer, Atlas V Program, Aerospace Corporation
"I used EasyFit to try and describe my complicated data set, and I was able to quickly overlay it with different
distributions. I found the best distribution, and I was able to easily dive deeper. Great program to use, especially
if you are unsure about what kind of data you might have."
Alexander R. Martinez, Mechanical Engineer, Fleet and Prototype Test Engineering, Gas Turbine Technology Lab, GE Energy

"Being a wind resource analyst, I usually need to fit my frequency data to a very specific function.
Most curvefit programs I tried in the past would make that very difficult, while not giving me a
very good fit. Easyfit professional, especially with its add-ins to Excel where my data lives,
made it much easier to find the distribution parameters I am looking for. This is especially important
to me because the distributions I usually work with are not standard in the industry, either."
Margo Guda, Manager & Senior Scientist, Fundashon Antiyano Pa Energia, Netherlands Antilles
"We needed a distribution-fitting tool that would work well with Excel. We've found EasyFit to be
easy to set up, fast, and accurate. We were pleased to get the added bonus of a number of custom Excel

what distributions these metrics follow. We have data sets of 23 metrics of 111 systems, that will result in
2553 fittings. By manual work in EasyFit, the operation becomes expensive, taking a lot of time. We are using the
SDK to automate this work, auto-generating the graphs and best fit distributions for us."
Tarcisio Filo, Researcher, University Federal of Minas Gerais, Brazil
"I had a wonderful experience with EasyFit as a statistical software as far as my thesis was concerned. EasyFit
made the analysis of my data so easy and no wonder it is called EasyFit. It helped me to fit statistical distributions
to the flood loss data in the 50 States of the United States without any problem. Also, anytime I had a question,
instant feedback was provided which I very much appreciated."
Ebenezer Osei, Student, Virginia Commonwealth University, USA
"I have been working as a Telecommunications Engineering teacher for the past seventeen years, and I can
attest that distribution fitting problems always come up in this area. Though I was introduced to EasyFit
not long ago, I have already found in it a superb and accurate way for solving those problems easily and quickly.
Additionally, the StatAssist tool has served to me and to my students as a simple, yet precise reference
with a great didactical appeal. I am also happy to see that the built-in library is being constantly updated
to include new distributions that will widen the already broad range of applications of EasyFit."

Frechet distribution is! Thanks!"
Elizabeth Browning, Student, LeTourneau University, USA
"I have used Easyfit for a number of years to look at data distributions and make sense of what underlies
them. It is a very easy program to use and the statistics and diagrams have been very helpful in writing
up the results and deciding which distributions are most sensible. I have also found the people at MathWave
Technologies to be very helpful and efficient when I have needed to interact with them."
Geoffrey Soutar, Winthrop Professor, University of Western Australia Business School, Australia
"I like EasyFit because of its user friendly interface and seamless integration in Excel. I can quickly check
the distribution fit and obtain parameters of the distributions. The XL package is especially useful to process
all necessary information within Excel and then plot all the graphs that I need. It makes the stat analysis
of my test data quick and easy. The tech support is prompt and helpful. The price for Academic Licence is very
friendly, too. I recommend it to my colleagues and students."
Alexander Salenikovich, P.Eng., Ph.D., Associate Professor, Université Laval, Canada
"We would like to congratulate you on your EasyFit software. Our research group at the Engineering Faculty of Stellenbosch
University use failure statistics in reliability modelling for the rail industry. Before we 'discovered' your software,
we mainly used linear regression to determine distribution parameters for datasets. Not only is it time consuming and limited
in capability, but a change in the dataset requires a manual re-calculation of parameters. With EasyFit we could easily compare
different distributions and the goodness of fit on a dataset, and the parameters correlated with our linear regression.
We are equally impressed with the Excel interface which makes an engineer's life easy!"
Pieter Conradie, P.Eng., Research Engineer, Stellenbosch University, South Africa
"MathWave's EasyFit software is, far and away, a superior data analysis program and easily surpasses its
competition. I have tried several similar programs, giving them decent scrutiny from the perspective of a project
manager and as an end user. I can attest that the benefits Mathwave claims for EasyFit are true: it's incredibly
easy to use from startup onward, and the savings of time (and expense) are immediately apparent. Then there's the
speed of its calculations, the clear graphics, plus the fast access and breadth and quality of its outputs,
which hold up strongly throughout a variety of input data sets. EasyFit's trouble-free integration and quick access
into MS Excel is another major plus. Altogether the quality, capabilities, and benefits from EasyFit should be
experienced if you're serious about your data analysis. At the end of the day, you're confident your own work is
much better understood and useful because of EasyFit. There isn't anything I can say that's better than that. "
Neil Weinberg, Corporate Trainer and Project Manager, Cincinnati, Ohio, USA
"I find EasyFit quite a useful package by any standards. It enables one fit distributions and compare among
a pool of many simple component distributions for the distribution of best fit. One gets back parameter values
of fitted distributions, ranking of distributions according to their fit, and further, one can view plots
for all the fitted distributions. One can view plots of statistical functions such as Harzard functions and
Survival functions for the available distributions through StatsAssist. It is even possible to export graphics
in most forms such as .eps, .bmp, .jpeg among others, enabling use of the graphics in Latex and other
environments (.pdf is probably something worth adding). It is worth noting that new users will use EasyFit
on their first attempt. It is so user friendly and addictive, when you have data that has been bothering you.
Thanks to the authors of EasyFit."
Nelson Owuor, Postdoctoral Student, Swedish University of Agriculture Sciences - SLU, Sweden
"I discovered Easyfit through a recommendation from a professor in college that I study. I am currently
working on series of data of extreme rainfall values, and soon discovered the enormous potential of adjusting
various probability distributions and seeing which one best fits the data. One of its major advantages is the
saving of time. It's easy to imagine the countless hours I would lose if I not used Easyfit. The computation is
very fast, stable and easy-to-use. Strongly recommended."
Alexandre Palma, Master Student, Institute of Geography and Spatial Planning, Portugal
"I think EasyFit is a valuable software for educational goals. The most
interesting feature of it for me is its ability to draw statistical
graphs due to the parameters which we provide: we can change the parameters
freely and see how the graph will change. It is very helpful for the
comprehension of various statistical distributions."
Amir Hossein Nikfal, M.S. Student in Meteorology, University of Tehran, Iran
"I always use EasyFit in exploratory data analysis to identify the best distribution fitting
data and to teach my students the fundamentals associated with the frequency distributions.
It's simple, fast, direct, reliable and inexpensive. Simply an indispensable tool for researchers
George Amaro, Researcher, Brazilian Agricultural Research Corporation, Brazil
"EasyFit has been a great facility in handling gene expression data sets with big number of sample variables.
It is through the software I learnt about the Fatigue Life distribution. The interactive graphs opened the hidden
avenues of the data that led to the conclusive interpretation of the dataset. It has been of tremendous help in the
exploratory data analysis of the dataset and eventually in the final phase of model fitting..."
Uzma Nawaz, Ph.D. Scholar, Bahauddin Zakariya University, Pakistan
"EasyFit was fantastic to me in the context of manage and analysis of large biological and genomics
data sets. It worked very easy, quick and precise. It is best alternative software for use in the analysis
of genomics data where researcher have a challenge with the huge and vital genomics data."

As a rainfall analysis researcher, I find it most suit the purpose for my research paper. It is a really helpful
software. Recommend it to whoever are dealing with probability distribution problems."
Mike Leong, INTI International University, Malaysia
"If you want to be sure that the distribution of your data accurately reflects reality, then EasyFit
is the only program that does everything you could ever wish for. The integration with Excel functions
and the extensive help notes go a long way towards simplifying what would otherwise be a tedious and
intimidating statistical exercise."
Keith Barnett, Amateur Meteorologist, Australia
"EasyFit is an amazing software both for occasional and frequent statistical analyses. The best way is to try
it out for no description can be a substitute for hands on experience. As a general idea, without prior knowledge
and help, it took me about ten to fifteen minutes to run the software on real live data. The simplicity of
application without loss of accuracy is a major plus. A General Extreme Value analyses on a sample of 75 values
took one minute as compared to some 15 minutes to solve the same problem in Excel."
F. Fahlbusch, Ph.D., Civil Engineer Retired
"Inputting directly from an Excel sheet and automatically using the data is very easy.
I really like the fact that you can work with summarized data from Excel bins and frequencies rather than the
raw data. Sometimes you have a reason for defining the bin width that may not be consistent with the best bin
width from a theoretical basis, or the summarized data is what you want to fit instead of the raw data.
I like the ability to do multiple fits and have them ranked by Goodness of Fit so quickly."
Larry J. Kasper, CPA, CVA, CBA
"EasyFit does not only speed up my data analysis task, but also helped me in understanding
several complex probability distributions... Besides, the customer support

"I enjoy examining butterfly migration patterns. Excel does not have a very robust set of statistical
analysis tools for modeling extreme distributions. EasyFit fills that void with a very extensive set of
worksheet formulas. Thanks, MathWave!"
Joseph Spain, Retired, North America
"I was preparing a manuscript for submission to a scientific journal, and had two very large data
sets of approximately 190,000 and 160,000 values, and I needed to test for the best statistical distribution
for each of them. I have limited experience in statistics, and I did not have access to any of the large
and expensive statistical packages. I investigated several options available on the Internet, and EasyFit
did all that I wanted, and was very straightforward to use in the trial version. I purchased an Academic
License, and it handled the very large data sets with ease. Various plotting options and goodness
of fit tests were easy to use, and the help section was particularly instructive for a
statistical novice such as myself."
"EasyFit provides a seamless and quick connection with Excel. It is extremely rapid and uses the three
widely used distribution fitting tests: Anderson-Darling, Kolmogorov-Smirnov and Chi-squared tests. The
package has many uncommon distributions such as the Gumbel, which is used extensively in extreme value theory.
An example would be extreme wind speeds, charting flood data among others. The program also has the Rayleigh
distribution which has applications in the analysis of wind speeds and in wind farms. There is also the
Birnbaum-Saunders distribution which is appropriate for describing cumulative degradation processes.
The aforementioned distributions among others are not found in the usual commonly used packages but are
nonetheless of crucial importance in analyzing many natural and financial data sets."
Michael London, Former Analyst, Chamber of Mines of South Africa, South Africa
"As a retired Telecommunication Engineer, I have been using distribution fitting software for decades. The list of
programs I used is long and, of course, all did the fit. But EasyFit to me is quite different. It has what I need -
a detailed and practically relevant knowledge base around 50+ distributions. It does what I want - a quick trustworthy
fit based on a self explanatory user interface. Data goes in and out with ease, and the assortment and display of
distributional data is exhaustive. The perfect integration into Excel gives it the ultimate edge since this is where
I do most of my work. A tremendous tool in the true sense: pops in when needed, works smoothly while I concentrate
on my real task, fitting distributions being only one step in a program."
H. Dieter Zimmermann, Telecommunication Engineer, Private Researcher, Dominican Republic
"As a Chinese software reseller, I find it very comfortable to work with MathWave.
