Factor selection using the least absolute shrinkage and selection operator (LASSO) logistic regression. A The LASSO coefficient profiles of the 40 candidate variables. The binomial deviance is plotted versus log (λ). B Tuning parameter (λ) selection in the LASSO logistic regression performed using tenfold cross-validation via the minimum criteria. A coefficient profile plot is produced versus the log (λ). The left vertical line represents the minimum error, and the right vertical line represents the cross-validated error within 1 standard error of the minimum
