Description

This function is used to compute the incomplete beta function.

Usage

ibeta(x, a, b, log = FALSE, reg = FALSE)

x	a numeric vector in the range [0,1], the point at which the incomplete Beta function is evaluated.
a	non-negative numeric vectors, the first parameter of the incomplete beta function.
b	non-negative numeric vectors, the second parameter of the incomplete beta function.
log	logical; If TRUE, return the log incomplete beta function.
reg	logical; If TRUE, return the regularized incomplete beta function. Same as the Mathematica definition.
