stats_dens_chisquare — Probability density function of the chi-square distribution
Returns the probability density at x
, where the
random variable follows the chi-square distribution of which the degree of
freedom is dfr
.
x
The value at which the probability density is calculated
dfr
The degree of freedom of the distribution
The probability density at x
or false
for failure.
