rf - Random numbers from the F distribution (inversion method)
Calling Sequence
- rf(n,df1,df2)
Parameters
-
n : positive integer or a vector [lig,col] of integers
-
df1,df2 : degrees of freedom
-
x : n-vector or a n-matrix of random numbers chosen from Fisher-Snedecor distribution with df1 and df2 degrees of freedom.
Description
Random numbers from the F distribution (inversion method)
The F law with degrees of freedom df1 and df2 is the law of
(X/df1)/(Y/df2) where X and Y are independent Chisquare random
variables with one degree of freedom.
