Figure 2. LASSO coefficients as a function of lambda.

Figure 2

Lambda represents a parameter in the regularization term. As lambda becomes very large, the LASSO yields the null model, where all coefficient estimates become zero. When moving from left to right in our plot, we observe that the LASSO models initially include many predictors with high magnitudes of coefficient estimates. However, with increasing lambda, the coefficient estimates gradually approach zero.

PLR: platelet-lymphocyte ratio; Eosino: eosinophils; WBC: white blood cells; RBC: red blood cells; LASSO: least absolute shrinkage and selection operator.
