Multiple Linear Regression: Curvilinear (quadratic cubic) and Interaction

In this video we perform a linear regression, looking at curvilinear regression and interaction regression. Curvilinear refers to fitting different trends relating the IV (quadratic, cubic etc). Interaction refers to fitting two main effects (2 numerical IVs) and their interaction term. The assumed knowledge is the videos earlier in the series, which covers univariate, bivariate, correlations, ANOVA table, coefficients, t-tests, f-tests, and checking assumptions.
