Description
Computes the normalizing constant in the log scale
usign the LogSumExp trick to avoid numerical issues (See details).
Usage
1
compute_logz(loglambda, nu)
Arguments
loglambda
A vector of logarithm of the λ
parameter.
nu
A vector of dispersion parameters ν.
Details
logspace_add(a, b) = log(exp(a) + exp(b)) = b + log(1 +
exp(a - b)), where b > a.
Value
A vector with the logarithms of the resulting
constants.
