A mathematical model comparing how one or more independent variables affect a continuous dependent variable

residual error

NA

coding scheme

How to represent categorical variables with numbers for use in models

simulation

Generating data from summary parameters

dependent variable

The target variable that is being analyzed, whose value is assumed to depend on other variables.

independent variable
