Stixbox Function 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.
