| Abstract: | Based on P-splines,semi-parametric generalized power Weibull regression models are studied in this work,meanwhile,the parameter estimators are obtained.On the other hand,several diagnostic measures are derived based on case-deletion model.Finally,some simulated examples are given to illustrate our statistic through Monte Carlo simulations. |
