What are the advantages and disadvantages of dummy coding and effect coding? When does it make sense to use one or the other? How does each one work, really? In this webinar, we’re going to go step-by-step through a few examples of how dummy and effect coding each tell you different...
To apply the procedures introduced in these papers, called weighted effect coding, procedures aremade available for R, SPSS, and Stata. For R, we created the‘wec’ packagewhich can be installed by typing: install.packages(“wec”) 转自:http://www.rensenieuwenhuis.nl/weighted-effect-coding-...
