Cumulative distribution function - Gausso-arithmetic scale

This function performs the empirical calculation of the cumulative distribution function of a random vector whose distribution is supposed to be normal. The CDF of input vector is represented in a gausso-arithmetic scale and tested in a linear regression. The corresponding coefficient of determination indicates the normality of the CDF.
The function is similar to "normplot" function (from MATLAB Statistical Toolbox) but requires no toolbox.
