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.
