β1 = 0.0, β2 = 0.1. S1–S9 denote the nine scenarios listed in Table I. Bias and SE are the bias and standard error of the parameter estimator. SEE is the mean of the standard error estimator. CP is the coverage probability of the 99% confidence interval. PW is the type I error/power for testing zero parameter value at the 0.01 nominal significance level. Each entry is based on 10,000 replicates.
