Homogeneity test based on Bootstrap method of risk difference for multi-group bilateral data
Under the Dallal model,three statistics are constructed to study the homogeneity test of risk differences for small sample multi-group bilateral data.Compared the performance in statistical test process of asymptotic meth-od and Bootstrap method with the small sample case by means of Monte-Carlo simulation,the result shows that the Bootstrap method performs better in the empirical type Ⅰ error rate and power.In particular,the Bootstrap method based on the Score test exhibits a relatively robust type Ⅰ error rate,high power,and optimal testing performance.
