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.
