seminr fSquared Function

Description

The fSquared function calculates f^2 effect size for a given IV and DV

Usage

fSquared(seminr_model, iv, dv)

Arguments

seminr_model	A seminr_model containing the estimated seminr model.
iv	An independent variable in the model.
dv	A dependent variable in the model.

Value

A matrix of the estimated F Square metric for each construct.
