Macro: boxcoxdens
Description: shows the change in the density before and after a Box-Cox transformation of x

Usage: boxcoxdens (x, p)
Input:
x n x q
p scalar

Example:
; loads the library stats
library("stats")
; loads the library graphic
library("graphic")   
; loads the library graphic
library("smoother")   
; reset random generator 
randomize(0)
; generate x (skewed)
x = 0.05+0.9.*uniform (250)
x = qfc (x, 2)
; show the densities
boxcoxdens(x, 0)
Result:
shows the density of the data before and after the
Box-Cox transformation.
