This chapter completes our investigations into linear models and their extensions. Not to fear, there is a whole wide world of statistics still out there for you to explore. In the final weeks of class, we will look at what to do when we have multiple correlated response variables (multivariate statistics), what to do when we have tons of explanatory variables but no idea how to meet assumptions of linear models we’ve discussed so far (classification and regression trees) or when we have non-linear relationships that can be common in biology.
