Question:
This could include graphs of the independent variables against the dependent variable, a correlation matrix to argue the inclusion/exclusion of variables in the model, the R2 values, the standard errors, the coefficients of the model (with their units), the significance of the coefficients (p-values), and/or any other type of analysis we have covered in the first five weeks of the course. Weave these items into a story about how you determined that your model is the best one for the data set given.
