Description

Functions for some basic operations with seasons.

Usage

pdSafeParOrder(p)

Arguments

p

autoregression order, a vector of integers.

Details

pdSafeParOrder(p) modifies the periodic AR order specified by vector p. The modified order is such that the correspondence between autocovariances and partial autocorrelations is one-to-one, see the references for details.

Value

a vector of integers
