Wald transformation-based confidence interval for a coefficient of variation of Gamma distribution with applications to PM 2.5 dispersion measurement

Accurate estimation of the coefficient of variation (CV) is essential for assessing the variability of environmental pollutants such as fine particulate matter (PM2.5). This study proposes a Wald transformation-based (Wald-TB) confidence interval for the CV of Gamma-distributed d...
