WebJan 20, 2014 · This in fact does not depend on the precision of Scipy's gammaln and betaln. The issue is that for large N, gammaln (N+1) is of the same order of magnitude as gammaln (N), but much bigger than gammaln (N+1)-gammaln (N). As a consequence, when you compute the difference, you lose ~ log10 (gammaln (N)) digits of precision.
