The original version of this article unfortunately contained a typographical mistake in one of the main formula. In Section 3, “A New Effect Size Index”, subscript “1” is missing in Eq. 8. The correct Eq. 8 is given below:

(8) $\begin{array}{c}{\hat{S}}_{\beta }\left(\theta \right)={\left(\text{max},\left(0,,,(T_{m_1}{\left(\hat{\theta }\right)}^2-m_1),/,(n-m)\right)\right)}^{1/2}\end{array}$ \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\begin{aligned} \hat{S}_{\beta }(\theta )=\left\{ \hbox {max}\left[ 0, (T_{m_1}(\hat{\theta })^2-m_1)/(n-m)\right] \right\} ^{1/2} \end{aligned}$$\end{document}
