Learning Statistics: Concepts and Applications in R Season 1 Episode 20 Polynomial and Logistic Regression

Polynomial regression is a form of regression analysis in which the relationship between the independent and dependent variables is modelled as the power of a polynomial. Step functions fit smaller, local models instead of one global model. Or, if we have binary data, there is logistic regression, in which the response variable has categorical values such as true/false or 0/1.
