Robustness Study of the Sequential Testing Procedures for the New Weibull-Pareto Distribution

Sequential testing procedures are developed for testing the hypotheses regarding the parameters of the New Weibull-Pareto Distribution (NWPD). Theoretical expression for the operating characteristics (OC) and average sample number (ASN) functions are derived for the scale parameters of the distribution. The robustness of the SPRT’S in respect of OC and ASN functions is studied, when the distribution under study has undergone a change. The results are presented through Tables and Graphs, so that one can see the numerical evaluated departures in OC and ASN functions
