Identifying Key Variables And Interactions In Statistical Models Of Building Energy Consumption Using Regularization, David Hsu Mar 2015

Identifying Key Variables And Interactions In Statistical Models Of Building Energy Consumption Using Regularization, David Hsu

David Hsu

Statistical models can only be as good as the data put into them. Data about energy consumption continues to grow, particularly its non-technical aspects, but these variables are often interpreted differently among disciplines, datasets, and contexts. Selecting key variables and interactions is therefore an important step in achieving more accurate predictions, better interpretation, and identification of key subgroups for further analysis.

This paper therefore makes two main contributions to the modeling and analysis of energy consumption of buildings. First, it introduces regularization, also known as penalized regression, for principled selection of variables and interactions. Second, this approach is demonstrated by ...
