icdf
              Return the inverse CDF of a univariate distribution evaluated at p.
 icdf is a wrapper for the univariate quantile distribution functions
 (iCDF) available in the statistics package.  See the corresponding functions’
 help to learn the signification of the parameters after p.
 x = icdf (name, p, A) returns the iCDF for the
 one-parameter distribution family specified by name and the
 distribution parameter A, evaluated at the values in p.
 x = icdf (name, p, A, B) returns the
 iCDF for the two-parameter distribution family specified by name and
 the distribution parameters A and B, evaluated at the values in
 p.
 x = icdf (name, p, A, B, C)
 returns the iCDF for the three-parameter distribution family specified by
 name and the distribution parameters A, B, and C,
 evaluated at the values in p.
name must be a char string of the name or the abbreviation of the desired quantile distribution function as listed in the followng table. The last column shows the number of required parameters that should be parsed after x to the desired iCDF.
