| Abstract: | The regression credibility models play very important role in study of insurance.In this paper, the score tests of autocorrelation is discussed for the regression credibility model with linear trend.Firstly, the score test statistic is derived for the existence of autocorrelation.Then the power simulation of the statistics is given by using the Monte-Carlo method,which shows that the test statistics has the excellent power.Finally,the obtained test method is illustrated by the private passenger automobile data. |
