| Resumo: | Many practical problems involving linear models has a step that consists in reducing
the number of variables of the model, either it is very expensive to deal with too many
variables or because some of the variables are able to explain the response satisfactorily.
We can cite among such methods of reducing the number of variables of a linear model,
the principal component analysis, best subset selection, forward stepwise selection, etc. In
this work, we present how to use the elitist genetic algorithm in order to select a collection
of variables for a linear model. Besides that, we show the convergence of the elitist genetic
algorithm to the set of all possible populations containing a solution of the problem under
study, at the same time we will obtain solutions to the variable selection problem using
the convergence of the elitist genetic algorithm. |
