This paper considers several confidence intervals for estim ating the population coefficient of variation based on parametric, nonparametric and modified m ethods. A simulation study has been conducted to compare the performance of the existing and new ly proposed interval estimators. Many intervals were modified in our study by estimating the va riance with the median instead of the mean and these modifications were also successful. Dat a were generated from normal, chi-square, and… Expand

Adjusted generalized confidence intervals for the common coefficient of variation of several normal populations

TLDR
The results showed that the GCI and AGCI methods were higher than or close to the nominal level in all cases and MOVER was better than the other methods because it provided the narrowest average length. Expand
