Improvement on Testing and Estimation While Presenting Autocorrelation:Testing for Autocorrelation and Parameter Estimation Based on the Autoregressive Distributed Lag Model

The test for autocorrelation and parameter estimate on model presenting autocorrelation is an important part of basic econometrics.Original model with autocorrelation is transformed into autoregressive distributed lag model.In this paper,the test for autocorrelation and parameter estimate was discussed.The test for autocorrelation based on the autoregressive distributed lag model was presented.At the same time,the estimation for the autoregressive distributed lag model was given.
