# Chapter 10 Further capabilities in R: Assumptions, Diagnostics, Model Criticism

At this point in this document, we have covered essentially all of the methods that we first utilized in SPSS and have added several others into the arsenal of tools. The document simultaneously tried to weave conceptual integration/review into the templates for accomplishing the analyses with R. The remainder of the document extends the set of analyses to things not yet covered in the course. This includes resampling methods, regression diagnostics and influence analysis, model criticism, models with more than two IVs, and models with categorical variables. Much of the following are presented with the dual goals of R instruction and further consolidation of the conceptual framework that comprises linear modeling with multiple IV’s and serves as a template for conceptual elaboration of those topics at later points in time.
