stats_dens_cauchy — Probability density function of the Cauchy distribution
Returns the probability density at x
, where the
random variable follows the Cauchy distribution whose location and scale are
ave
and stdev
, respectively.
x
The value at which the probability density is calculated
ave
The location parameter of the distribution
stdev
The scale parameter of the distribution
The probability density at x
or false
for failure.
