pf

The F (or Fisher Snedecor) cumulative distribution function

Calling Sequence

F = pf(x,df1,df2)

Parameters

x

real

df1,df2

degrees of freedom (x,df1,df2 can be scalar or matrix with common size)

F

for each element of x, F=Prob((X/df1)/(Y/df2) < x) where X and Y are independent Chi-square random variables with one degree of freedom

Description

The F (or Fisher-Snedecor) cumulative distribution function
