Description

Calculates confidence interval for partial eta-squared in a fixed-effects ANOVA

Usage

1
get.ci.partial.eta.squared(F.value, df1, df2, conf.level = 0.9)

Arguments

F.value

The F-value for the fixed-effect

df1

Degrees of freedom for the fixed-effect

df2

Degrees of freedom error

conf.level

Confidence level (0 to 1). For partial eta-squared a confidence level of .90 is traditionally used rather than .95.
