Discover how linear regression works, from simple to multiple linear regression, with step-by-step examples, graphs and real-world applications.

We call these “slope values”, regression coefficients or beta coefficients. The main distinction between different types of regression model is that they are used for different types of outcome (eg, ...

The most basic regression relationship is a simple linear regression. In this case, E (Y | X) = μ (X) = β0 + β1X, a line with intercept β0 and slope β1.

Linear and logistic regression models are essential tools for quantifying the relationship between outcomes and exposures. Understanding the mathematics behind these models and being able to apply ...
