Webb6 nov. 2024 · In this article we’ll take a brief tour of the XGBoost package in R. Previously, I wrote an overview article “Gradient Boosting and XGBoost” which you might wish to read first in order to get some background before digesting the code in this article. As a quick launch pad for this article, XGBoost is an abbreviation for eXtreme Gradient Boosting. WebbPlot Observed versus Predicted Results in Regression and Classification Models Description This function takes an object (preferably from the function extractPrediction) and creates a lattice plot. For numeric outcomes, the observed and predicted data are plotted with a 45 degree reference line and a smoothed fit.
