logZ_c: Calculate the Normalizing Constant in log scale for...
In thomas-fung/mpcmp: Mean-Parametrized Conway-Maxwell Poisson (COM-Poisson) Regression
logZ_c R Documentation
Calculate the Normalizing Constant in log scale for COM-Poisson distribution
The calculation of the function logZ will be performed here. This function is
used to approximate the normalizing constant for COM-Poisson distributions via
truncation. The standard COM-Poisson parametrization is being used here.
Description
It is assumed that vectors log_lambda & nu are of equal length.
Usage
logZ_c(log_lambda, nu, summax)
Arguments
log_lambda
rate parameter in log scale.
nu
dispersion parameter, straightly positive.
summax
maximum number of terms to be considered in the truncated sum.
Details
This function was originally purposed in the cmpreg package of Ribeiro Jr,
Zeviani & Demétrio (2019).
