The Effects of Variable Selection Methods on Linear Regression-Based Effort Estimation Models
Pages 98 - 103
Abstract
Stepwise regression has often been used for variable selection of effort estimation models. However it has been criticized for inappropriate selection, and another method is recommended. We thus examined the effects of Lasso, which is one of such variable selection methods. An experiment with datasets from PROMISE repository revealed that Lasso-based selection stably selected better variables than stepwise in predictive performance. We thus concluded Lasso-based selection is preferable to stepwise regression.

Kernel methods for regression model based on variable selection
The aim of this paper is to get a sufficiently smooth regression function using kernel method based on the concept of variable selection for regression model. It is essential point that the procedure does not contain the concept of the regularisation. ...
Robust nonnegative garrote variable selection in linear regression
Robust selection of variables in a linear regression model is investigated. Many variable selection methods are available, but very few methods are designed to avoid sensitivity to vertical outliers as well as to leverage points. The nonnegative garrote ...
Variable selection using a smooth information criterion for distributional regression models
AbstractModern variable selection procedures make use of penalization methods to execute simultaneous model selection and estimation. A popular method is the least absolute shrinkage and selection operator, the use of which requires selecting the value of ...
