Activity Overview
To investigate the idea of transformations of numerical variables to aid in the assessment of goodness of fit, using residual plots, transformed plots and associated statistics.
Objectives
- Introduce data transformation for variables to improved fit
- Residual analysis of numerical bivariate relationships
- Creation of an analysis template for visualization and testing of transformations
Vocabulary
- Statistical variable
- Linearising, transformation of variables
- Residual analysis
