• USING EASY FIT SOFTWARE FOR GOODNESS-OF-FIT TEST AND DATA GENERATION

Hossein Mehrannia*, Alireza Pakgohar

Abstract


Data Fitting process involves using certain statistical techniques which allow us to estimate fitness parameters in accordance to data sample. One advantage of using software to fit the data and interpreting probability data is that they are able to automatically fit data with a variety of known distribution patterns simultaneously. These methods are preferred especially in cases which you have very little or no information about the base distribution pattern in data, and desire to find the best distribution type. EasyFit is a data analyzer and simulation software which allows us to fit probabilistic distributions to given data samples, simulate them, choose the best fitting sample, and implement the results of analysis to take better decisions. This software can be used as a Windows compatible program, and also as an add-on to Excel spread sheets. This study reviews performance, the abilities, and imbedded statistical tools of this software.
