Modern Regression Analysis in R

Introduction to Statistical Models

In this module, we will introduce the basic conceptual framework for statistical modeling in general, and for linear regression models in particular.

Linear Regression Parameter Estimation

In this module, we will learn how to fit linear regression models with least squares. We will also study the properties of least squares, and describe some goodness of fit metrics for linear regression models.

Inference in Linear Regression

In this module, we will study the uses of linear regression modeling for justifying inferences from samples to populations.

Prediction and Explanation in Linear Regression Analysis

In this module, we will identify how models can predict future values, as well as construct interval estimates for those values. We will also explore the relationship between statistical modelling and causal explanations.

Regression Diagnostics

In this module, we will learn how to diagnose issues with the fit of a linear regression model. In particular, we will use formal tests and visualizations to decide whether a linear model is appropriate for the data at hand.

Model Selection and Multicollinearity

In this module, we will study methods for model selection and model improvement.. In particular, we will learn when and how to apply model selection techniques such as forward selection and backward selection, criterion-based methods, and will learn about the problem of multicollinearity (also called collinearity).
