Methods and algorithms for a statistical approach in phylogenetics
Variation of substitution rates across sites is widespread among biological sequences. A gamma distribution, defined by a shape parameter, is generally used to model... -
On the infinite divisibility of inverse Beta distributions
We show that all negative powers B_{a,b}^-{s} of the Beta distribution are infinitely divisible. The case b<1 follows by complete monotonicity, the case b > 1, s...
