lme.dscore {EMAtools} | R Documentation |
Calculate d scores from an lme4 or nlme object
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")
