# Topic - Bentley University MA252

MA252 is an undergraduate statistics course at Bentley University that focuses on model building using regression. The description from the course catalog can be found here.

It covers simple linear regression, multivariate linear regression, logistic linear regression, model building, transformations, and interactions.

## Simple Linear Regression

## Multivariate Linear Regression

- How to fit a multivariate linear model
- How to add an interaction term to a model
- How to add a polynomial term to a model
- How to add a transformed term to a model
- How to compute a confidence interval for a regression coefficient
- How to compute adjusted R-squared

## Model Building
