Abstract:In this paper, we establish some deviation inequalities and the moderate deviation principles for the least squares estimators of the parameters in the threshold autoregressive model under the assumption that the noise random variable satisfies a logarithmic Sobolev inequality.
Keywords:Threshold autoregressive model  least square estimator  moderate deviations  logarithmic Sobolev inequality
