Model Selection and Evaluation

Model Selection and Evaluation

If there are too many irrelevant variables in a linear regression model, the estimates for the relevant ones are negatively affected. Therefore, it is important both in theory and practice to be able to find the model which includes only the most important variables. Traditional approaches consider information criteria. The method of LASSO has become more popular in the past decade.
