Figure 2From: Prediction intervals for future BMI values of individual children - a non-parametric approach by quantile boosting Results from the non-linear setup in the low-dimensional scenario: Boxplots represent the distribution of y test . Black solid lines show the true conditional quantiles, while the colored lines represent the fitted conditional quantiles from 100 simulation runs for quantile boosting (left) and quantile regression forest (right).Back to article page
