Effect on Weightloss of Age, Calorieintake, Exercise, Interaction, 64 Patients, Traditional Versus Regularized Regressions

In this chapter Traditional and regularized regression analysis was applied to assess the effect of age, calorieintake, exercise, and their interactions on weightloss. The best result from the regression analyses was obtained by the Elastic Net regularized regression. Also Ridge and Lasso produced pretty well. The standardized Traditional regression produced 2 poor and 2 strong correlations. The unstandardized Traditional regression produced two significant p-values, < 0.001 and 0.002, the factors of which had strong correlations in the standardized Traditional regression.
