Abstract:
In view of the actuality that the test for heteroscedasticity is supposed in fixed clusters,a test for heteroscedasticity in random clusters is proposed here.The method of variances parameterization is utilized to investigate the test for heteroscedasticity in Poisson-gamma regression model of longitudinal data.The composite tests for heteroscedasticity and random clusters are given.The statistic data of score test is obtained.A numerical example of the real data is given here to illustrate the effectiveness.
