}Beta functions.
Required Methods
fn inc_beta(self, p: Self, q: Self, ln_beta: Self) -> Self
Compute the incomplete beta function.
The code is based on a C implementation by John Burkardt. The original algorithm was published in Applied Statistics and is known as Algorithm AS 63 and Algorithm AS 109.
fn inv_inc_beta(self, p: Self, q: Self, ln_beta: Self) -> Self
Compute the inverse of the incomplete beta function.
The code is based on a C implementation by John Burkardt. The original algorithm was published in Applied Statistics and is known as Algorithm AS 64 and Algorithm AS 109.
fn ln_beta(self, other: Self) -> Self
Compute the natural logarithm of the beta function.
