Model the linear relationship between numeric response and one or more explanatory variables by fitting a linear regression model.
Details
This module will create a linear model, modelling one dependent variable as a linear combination of one or more independent variables. Linear regression is often used for the purpose of fitting a predictive model to dataset containing the response and predictor variables.
Linear regression can also be used to assess the relationship between different variables in a dataset and analyse whether the variance in some variables can be explained or modeled by linear combinations of other variables.
Output
The module output is the summary output of a linear model created in R. More details on this output can be found in the R documentation for lm.
