Use this module to fit a probability distribution to your quantitative data (continuous or discrete data), and to check the quality of the resulting fit.
Several probability distributions are available: Beta, Binomial, Negative binomial, Chi-square, Erlang, Exponential, Fisher, Fisher-Tippett, Gamma, GEV, Gumbel, Lognormal, Normal, Pareto, Poisson, Student, Uniform, Weibull.
XLSTAT allows you to directly enter the values of the parameters for the chosen probability distribution, or to automatically estimate them. Goodness of fit tests are automatically computed (Kolmogorov-Smirnov and Chi-Square).
