jax.scipy.special.multigammaln#
- jax.scipy.special.multigammaln(a, d)[source]#
The natural log of the multivariate gamma function.
JAX implementation of
scipy.special.multigammaln()
.\[\mathrm{multigammaln}(a, d) = \log\Gamma_d(a)\]where
\[\Gamma_d(a) = \pi^{d(d-1)/4}\prod_{i=1}^d\Gamma(a-(i-1)/2)\]and \(\Gamma(x)\) is the
gamma()
function.- Parameters:
a (ArrayLike) – arraylike, real-valued.
d (ArrayLike) – int, the dimension of the integration space.
- Returns:
array containing values of the log-multigamma function.
- Return type:
