Abstract

This study compares the restricted and unrestricted methods of bootstrap data generating processes (DGPs) on statistical inference. It used hypothetical datasets simulated from normal distribution with different ability levels. Data were analyzed using different bootstrap DGPs. In practice, it is advisable to use the restricted parametric bootstrap DGP models and thereafter, check the kernel density of the empirical distributions that are close to normal (at least not too skewed). In fact, 21600 scenarios were replicated 200 times using bootstrap DGPs and kernel density methods. This analysis was carried out using R-statistical package. The results show that in a situation where the distribution of a test is skewed, all the scores need to be taken into account, no matter how small the sample size and the bootstrap level are. Across all the conditions considered, models HR5UR and HPN5UR yielded much larger bias and standard error while the smallest bias values were associated with models HR5R (0.0619) and HPN5R (0.0624). The result confirms the fact that bootstrap DGPs are very vital in statistical inference.
