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.
