qf

The F (or Fisher-Snedecor) inverse distribution function

Calling Sequence

x = qf(p,df1,df2)

Parameters

p

probability

df1,df2

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

x

inverse at p of the F cumulative distribution function with degrees of freedom df1, df2

Description

The F (or Fisher-Snedecor) inverse distribution function The F law with degrees of freedom df1 and df2 is the law of (X/df1)/(Y/df2) where X and Y are independent Chi-square random variables with one degree of freedom.
