lme.dscore: Calculate d scores from an lme4 or nlme object

In EMAtools: Data Management Tools for Real-Time Monitoring/Ecological Momentary Assessment Data

Description

This will calculate Cohen's D for each effect in an lme4 object.

Usage

lme.dscore(mod, data, type)

Arguments

mod	An lme4 or nlme object
data	The dataset the lme4 or nlme object was drawn from
type	Either "lme4" or "nlme"

Value

A table of d-scores.

Note

lme4 and nlme models will produce slightly different estimates. This is because when using type="lme4", the numerator DF will be calculated using the Satterthwaite approximations to degrees of freedom (via the lmerTest package), whereas nlme includes Kenward-Roger numerator degress of freedom. If you have sufficent level-1 samples, the difference between models will be miniscule.

Examples

## Not run: model1<-lmer(DV~IV1+IV2+IV3+(1|subject),data=DATA_1)
 ## Not run: lme.dscore(model1,data=DATA_1,type="lme4")
