statistics: retval = pdf (name, x, …)

Return the PDF of name distribution function for value x.

This is a wrapper for the namepdf and name_pdf functions available in the statistics package. See the corresponding functions’ help to learn the signification of the arguments after x.

name must be a char string of the name or the abbreviation of the desired probability distribution function as listed in the followng table. The last column shows the maximum number of extra arguments that can be passed to the desired PDF.
