11.1 Suffix Marks Type of Function

The suffix is determined by the type of function according to the following table.

function outcome suffix
log probability mass function discrete _lpmf
log probability density function continuous _lpdf
log cumulative distribution function any _lcdf
log complementary cumulative distribution function any _lccdf
random number generator any _rng

For example, normal_lpdf is the log of the normal probability density function (pdf) and bernoulli_lpmf is the log of the bernoulli probability mass function (pmf). The log of the corresponding cumulative distribution functions (cdf) use the same suffix, normal_lcdf and bernoulli_lcdf.
