artransform: Mapping real valued parameters to stationary region

Description

Function artransform transforms \(p\) real valued parameters to stationary region of \(p\)th order autoregressive process using parametrization suggested by Jones (1980). Fortran code is a converted from stats package's C-function partrans.

Usage

artransform(param)

Arguments

param

Real valued parameters for the transformation.

Value

transformed The parameters satisfying the stationary constrains.
