micombine.F: Combination of F Statistics for Multiply Imputed Datasets Using a Chi Square Approximation

Description

Several $F$ statistics from multiply imputed datasets are combined using an approximation based on $\chi^2$ statistics (see micombine.chisquare).

Usage

micombine.F(Fvalues, df1, display = TRUE)

Arguments

Fvalues

Vector containing $F$ values.

df1

Degrees of freedom of the denominator. Degrees of freedom of the numerator are approximated by $\infty$ (large number of degrees of freedom).

display

A logical indicating whether results should be displayed at the console

Value

• The same output as in micombine.chisquare
