Changes in version 0.0.5 (2025-04-25) - Added linear model tree. Specifically, use parameter Xsplit as the splitting variable for ODT and fit a linear model for each split using the function "gmlnet". The corresponding parameter is split="linear". - Added the ensemble of ODT-based boosting trees,denoted by ODBT. - Changed the parameter "leafnode" to "type" in the function predict.ODT(), and for classification tasks, added category probability output. - Optimized some other known issues. Changes in version 0.0.4 (2023-05-28) - Fixed function VarImp(), adding the method of measuring the importance of variables with node purity, and now VarImp() can be used for both class ODT and ODRF. - When the argument “Xcat ! = 0”, i.e., the category variable in predictor X is transformed to one-of-K encode. however for the argument “NodeRotateFun=‘RotMatRF’ (‘RotMatRand’)“ run error, we have now fixed it. - Added predicted values of training data for class ODT and ODRF. - Fixed issue related to function predict.ODRF() when argument "weight.tree = TRUE". - Optimized some other known issues. Changes in version 0.0.3 (2023-03-16) - The function predicate.ODT() runs error when ODT is not split (depth=1), and we have fixed this bug. - We have fixed the function predict.ODRF() with arguments numOOB and weight.tree related issues. - We have fixed the functions plot.ODT(), VarImp() and plot.VarImp(). - We have fixed the argument 'lambda' of the functions ODT() and ODRF(). Changes in version 0.0.2 (2023-02-28) - We have now explained CART and Random Forest in the description text. - We have changed the Date field to a more recent date. - We have now exported the functions RandRot() and defaults(), and no longer need ODRF::: - We have removed par from plot.VarImp() and added on.exit to plot.prune.ODT(), and checked the code to make sure that it does not change the user's options, including par or working directory. - We have removed the random seed number in functions ODRF(), poune.ODRF(), online.ODRF() and plot_ODT_depth(). Changes in version 0.0.1 - Added a NEWS.md file to track changes to the package. - This is the first fully-functioning version of the package. It currently has no ERRORs, WARNINGs, or NOTEs from devtools::check().
