Confidence intervals for standardized effect sizes: theory, application, and implementation

Kelley (2007) — confidence intervals for standardized effect sizes

Result

noncentral-$F$/$t$/$\chi^2$ confidence intervals for $\eta^2$, $R^2$ and Cohen's $d$ under normal-theory ANOVA (MBESS).

Use

the standard applied route for $\eta^2$ intervals, assuming Gaussian errors and a fixed design; O6 replaces that assumption by $E S^4<\infty$ and a first-order limit.
