Selection of optimal predictors using the LASSO regression. Notes: a Determination of optimal regularization parameter λ of the LASSO model to select the optimal predictors for IFD deterioration. When log(λ) is -3.79, LASSO shows the best predictive performance with the minimum number of predictors and regression errors, where the coefficients of 27 out of 43 baseline variables are shrunk to zero. b The coefficient profile of LASSO. The trajectory of each IFD-related feature coefficient is observed in the LASSO coefficient profiles with the changing of the λ values. LASSO, least absolute shrinkage and selection operator; IFD, invasive fungal disease
