- Important to limit the number of factors in the model for 2 reasons: 
o Overfitting – When the number of factors is close to or larger than the number of data 
points the model might fit too closely to random effects 
o Simplicity – on aggregate simple models are better than complex ones. Using less factors 
means that less data is required and the is a smaller chance of including insignificant 
factors. Interpretability is also crucial. Some factors are even illegal to use such as race

# Week 5 Notes Variable Selection 
what do we do with a lot of factors in our models? 
variable selection helps us choose the best factors for our models 
variable selection can work for any factor based model - regression / classification 
why do we not want a lot of factors in our models? 
- overfitting: when the number of factors is close or larger than number of data points our model will 
overfit 
- overfitting: model captures the random effect of our data instead of the real effects
