Hello everyone,
I was wondering if anyone knows of an R package which will extract the
standardised effect size (r) and 95% confidence intervals for a single
continuous predictor in a mixed-effects model. For example, I have
model<-lme(damage~car+depth+wet,random=~1|id,data=data)
I need to find out the standardised effect size and confidence intervals of
'car', in a model with 'depth' and 'wet' included as covariates. I can
calculate the effect size manually, but obtaining exact confidence intervals
seems much more tricky. However, I expect somebody has developed a package for
R which will do this at the tap of a button, so any tips would be appreciated!
Many thanks
Sam Weber
