Model confidence bound for variable selection
Web23 sep. 2024 · A variable selection method is a way of selecting a particular set of independent variables (IVs) for use in a regression model. This selection might be an attempt to find a ‘best’ model, or it might be an attempt to limit the number of IVs when there are too many potential IVs. There are a number of commonly used methods which I call ... Web8 jul. 2024 · When choosing proper variable selection methods, it is important to consider the uncertainty of a certain method.

Webtainty of a certain method. The model confidence bound for variable selection identi-fies two nested models (upper and lower confidence bound models) contain-ing the true model at a given confidence level. A good variable selec-tion method is the one of which the model confidence bound under a certain confi-dence level has the shortest width.
