Ftest

Purpose

Inverse F test and F test.

Synopsis

fstat = ftest(p,n,d,flag)

Description

fstat = ftest(p,n,d) or fstat = ftest(p,n,d,1) calculates the F statistic fstat given the probability point p and the number of degrees of freedom in the numerator n and denomenator d.

fstat = ftest(p,n,d,2) calculates the probability point fstat given the F statistic p and the number of degrees of freedom in the numerator n and denomenator d.

Examples

a = ftest(0.05,5,8); returns the value 3.6875 for a, and

a = ftest(3.6875,5,8,2); returns the value 0.050 for a.
