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