WebDetails. OVERVIEW The purpose of Model is to combine many standard R function calls into one, as well as provide ancillary analyses such as as graphics, organizing output into tables and sorting to assist interpretation of the output, all from a single function. Currently the supported models are OLS regression, ANOVA and the t-test. Web24.2.2 A more complicated model. If we wanted to, we could continue to build up our model, moving the effects we’ve observed into the model to make them explicit. For example, we could include color, cut, and clarity into the model so that we also make explicit the effect of these three categorical variables:
