Auxiliary function for evaluating normalizing constant for the posterior of a fitted DLM. — eval_dlm_norm_const • kDGLM

Evaluates the normalizing constant for the posterior of a fitted DLM.

Usage

eval_dlm_norm_const(model, lin.pred = FALSE, safe.mode)

Arguments

model: fitted_dlm: A fitted_dlm object.
lin.pred: boolean: A flag indicating if the normalizing constant should be calculated using the linear predictors.

Value

A scalar representing the normalizing constant for the posterior of a fitted DLM.
