Erratum to: A Robust Effect Size Index

Erratum to: Psychometrika Vol. 85, No. 1, 232–246, March 2020 10.1007/s11336-020-09698-2

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:

$$\begin{array}{c}\hfill {\widehat{S}}_{\beta }(\theta )={\left\{\text{max},\left[0,,,(T_{m_1}{(\widehat{\theta })}^2-m_1),/,(n-m)\right]\right\}}^{1/2}\end{array}$$ 8
