randist/test.c samples the distribution and compares the resulting histogram with the pdf itself to see if they are compatible within statistical errors.
I understood the sampling part and the comparing part. What confuses me is the compatibility criteria. In particular, why the undimensionless sigma variable (a difference over a square root) is compare to a dimensionless value (a constant) ?
Thanks, Jerome
