Abstract:

We proposed the maximum likelihood method to estimate the parameters in a special timevarying parameter autoregression model (TVPAR(p) model). The maximum likelihood estimate results of all the unknown parameters were given.The stability of the TVPAR model was discussed. Simulation was used to illustrate the proposed estimation method.

Key words: TVPAR model, maximum likelihood estimation, stability
