Ftable-func

Definition:

The Ftable(x, m, n) function is the F distribution function with m and n degrees of freedom. x is usually called the significance level.

The F distribution is used in calculating confidence limits for parameters in nonlinear regression.

Parameters:

x

the significance level

m

the degrees of freedom of the numerator variance

n

the degrees of freedom of the denominator variance

Examples:

Ftable(0.95, 2, 15) = 3.68232

Ftable(0.95, 4, 10) = 3.47805
