Description Usage Arguments Value Author(s) Examples

Convenience function for computing the pointwise Akaike Information Criteria method from a varstan object.

aic(x)

`x`	A varstan object of the time series fitted model.

A numeric array of size R, containing the posterior samples of the AICc for a varstan object, where R is the number of iterations. If multiple chains are fitted, then the array is of length M*R, where M is the number of chains
