This tool is accessible via the [[File:CcComputeStat.png]] icon in the main upper toolbar or the 'Tools > Statistics > Compute stat. params (active SF)' menu.

= Description =

This tool fits a statistical distribution on the active scalar field of the selected entity.

Available distributions are:
* Gauss (aka [http://en.wikipedia.org/wiki/Normal_distribution Normal]) distribution
* [http://en.wikipedia.org/wiki/Weibull_distribution Weibull] distribution

= Procedure =

Select an entity (cloud or mesh) then call this tool.

A dialog will appear so as to let the user choose the distribution to fit:
[[File:Cc_fit_stat_params_distribution_dialog.jpg|center]]

Eventually CloudCompare will compute the corresponding distribution parameters and display the scalar histogram with a grey curve corresponding to the fitted distribution.

The distribution parameters are displayed above the histogram, and also in the [[Console]] (along with the [http://en.wikipedia.org/wiki/Chi-square_test Chi<sup>2</sup> test] result so as to get an evaluation of the fit quality).
