stats_dens_beta — Probability density function of the beta distribution
Returns the probability density at x
, where the
random variable follows the beta distribution of which the shape parameters
are a
and b
.
x
The value at which the probability density is calculated
a
The shape parameter of the distribution
b
The shape parameter of the distribution
The probability density at x
or false
for failure.
