Module statrs::function::beta [−] [src]

Provides special functions related to the beta function

Functions

beta	Computes the beta function where `a` is the first beta parameter and `b` is the second beta parameter.
beta_inc	Computes the lower incomplete (unregularized) beta function `B(a,b,x) = int(t^(a-1)*(1-t)^(b-1),t=0..x)` for `a > 0, b > 0, 1 >= x >= 0` where `a` is the first beta parameter, `b` is the second beta parameter, and `x` is the upper limit of the integral
beta_reg	Computes the regularized lower incomplete beta function `I_x(a,b) = 1/Beta(a,b) * int(t^(a-1)*(1-t)^(b-1), t=0..x)` `a > 0`, `b > 0`, `1 >= x >= 0` where `a` is the first beta parameter, `b` is the second beta parameter, and `x` is the upper limit of the integral.
ln_beta	Computes the natural logarithm of the beta function where `a` is the first beta parameter and `b` is the second beta parameter and `a > 0`, `b > 0`.
