Quantlet: grppn
Description: generates a probability-probability-plot to compare a variable with a normal distribution

Link:
Usage: bp = grppn (x{, col})
Input:
x n x 1 vector
col color
Output:
dp composed graphical object

Example:

; loads the library graphic

library ("graphic")

; generate a dataset with 160 observations

t  = (normal(25)-8)|(normal(25)+8)|normal(100)|(normal(10)+25)

; generate a pp-plot to compare t with a normal distribution

bp = grqqn (t)

; create a dispplay for plotting

d  = createdisplay (1,1)

; plot the pp-plot

show (d, 1, 1, bp)

Result:

shows a pp-plot
