View source: R/trunc_distr.R

Description

This function returns an approximation of P(X \in E1)/P(X \in E2), where X is a central F random variable with df1, df2 degrees of freedom.

Usage

1
TFRatioApprox(df1, df2, E1, E2)

Arguments

df1, df2

degrees of freedom of the F random variable.

E1, E2

"Intervals" objects or matrices where rows represents a union of intervals with positive and finite endpoints.

Value

This function returns the value of the approximation.
