A comparison of some modified confidence intervals based on robust scale estimators for process capability index
Abu-Shawiesh, Moustafa Omar Ahmed; Banik, Shipra; Kibria, B. M. Golam; Akyuz, Hayriye Esra (Sprınger Heıdelberg, 2020)This paper aims to compare the performances of modified confidence intervals based on robust scale estimators with classical confidence interval for process capability index (C-p) when the process has a non-normal distribution. ... -
A robust confidence interval based on modified trimmed standard deviation for the mean of positively skewed populations
Akyuz, Hayriye Esra; Abu-Shawiesh, Moustafa Omar Ahmed (Unıv Studı Salento, 2020)In this study, we propose a robust confidence interval which is adjustment of the Student-t confidence interval based on the trimmed mean and the modified trimmed standard deviation for the mean of skewed populations. The ...
