Two stepwise procedures based on variance estimators are proposed for selecting the significant variables in a general nonparametric regression model.

There are several automated feature selection methods, ranging from backward, forward or stepwise procedures, to further elaborated methodologies such as evolutionary programming.

The stepwise procedures of the VIA algorithm are described as follows: Step (1): Set v0(s) = 0 for each state s.

For that purpose several search algorithms have been devised, ranging from simple heuristic approaches [26, 27] which perform a "greedy" search of the best subsets of variables such as forward selection, backward elimination or stepwise procedures to further elaborate methodologies including simulated annealing [28] and evolutionary programming [29] such as genetic algorithms [30].

Due to the high number of baseline covariates collected in the study, only variables different at baseline at a 10% significance level and variables thought to be influential (country effect, treatment as mono- versus polytherapy) were entered into the initial joint model for compliance and were then reduced using stepwise procedures.

Stepwise procedures were not used.

Backward stepwise procedures were used.
