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
