inc_beta() [8/10]

double stan::math::inc_beta ( double  a, double  b, double  x  )

inline

The normalized incomplete beta function of a, b, with outcome x.

Used to compute the cumulative density function for the beta distribution.

Parameters

a	Shape parameter a >= 0; a and b can't both be 0
b	Shape parameter b >= 0
x	Random variate. 0 <= x <= 1

Exceptions

if	constraints are violated or if any argument is NaN

Returns

The normalized incomplete beta function.
