Webeffects models in R. In this supplement, we show how to use the lme() and gls() functions to reproduce the models introduced by Kenny and Hoyt (2009), and also introduce some extractor functions that can operate on the output from lme() and gls(), and can assist users in interpreting multilevel relationships. Notation WebIn practice, we would not know that the r 0 31 and we’d need to estimate it from the data. Our initial estimate is 0.31 but once we t our GLS model we’d need to re-estimate it as > cor(res[-1],res[-16]) [1] 0.35642 and then recompute the model again with r 0 35642 . This process would be iterated until conver-gence. daisy diamond cast
