For simple regression forests, predicting the conditional mean by nearest neighbor weights with scale = TRUE is now equivalent to the aggregation of means. The unscaled version proposed in can be obtained with scale = FALSE.} CHANGES IN party VERSION 1.2-4 (2017-12-13) o Bonferroni sometimes overcorrected (by taking constant variables into account). Spotted by Heidi Seibold. o Bugfix for long-standing problem in conditional variable importances by Dries Debeer. CHANGES IN party VERSION 1.2-3 (2017-04-10) o predict(, OOB = TRUE) in party < 1.2-0 was _correct_ and version 1.2-0 to 1.2-2 contained in incorrect "correction". The test set error and the out-of-bag error are now (again) roughly equal. There won't be any correlation between observations and out-of-bag predictions when the response is independent to all explanatory variables. Out-of-bag predictions in package partykit (>= 2.0-0) are now based on the same out-of-bag weights and the results from both packages are roughly equivalent. The issue was first spotted by Julian Karch and later by Andrew Sage. o comment on false alarms by maacheck / bcheck (email by Tomas Kalibera April 10, 2017) in party/src/*c CHANGES IN party VERSION 1.2-2 (2017-02-27) o free memory in src/Distributions.c (pointed out by Martin Binder) o register C routines CHANGES IN party VERSION 1.2-1 (2017-02-08) o fix a memory leak occuring while searching for surrogate splits in the process of predicting the terminal node ID o surrogate splits might have used statistics with slightly incorrect weights o party::ctree gives _same_ results as partykit::ctree (version >= 2.0-1 from R-forge) CHANGES IN party VERSION 1.2-0 (2017-02-06) o predict(, OOB = TRUE) relied on incorrect weights and gave suboptimal predictions. varimp() was not affected.

CHANGES IN party VERSION 0.9-99 (2008-10-28) o a suboptimal split was implemented when the best split corresponded to the last row of due to a coding error. This should have happend only very rarely, however, the glaucoma example is affected. CHANGES IN party VERSION 0.9-98 (2008-10-15) o don't compute ordering of censored variables (thanks to Brian D. Ripley for the report) o experimental version of partialPlot for cforests o teststat = "quad" and testtype = "Univariate" produced wrong criteria in the presence of constant exploratory variables.

Thanks to Henric Nilsson. CHANGES IN party VERSION 0.9-92 (2007-11-22) o predict() computed predictions for observations with zero weights (by passing them down the tree). This was already done this way by predict() but resulted in an error for ctree()s. o minbucket added to ctree_control() CHANGES IN party VERSION 0.9-91 (2007-09-26) o bugfix: NAs in factors lead to segfaults on 64bit machines as reported by Carolin Strobl o related to this: be more careful when splitting in variables containing missing values, especially factors. o add examples to regression tests o new function `proximity' (feature request by Henric Nilsson) CHANGES IN party VERSION 0.9-90 (2007-09-24) o new defaults for `control' argument of `cforest': unbiased forests are now grown by default o new defaults for binary classification tree visualization: stacked bar charts are used by default.

More careful revision of the predict and fitting code is needed. o predictions for cforest with multivariate response are now returned in a matrix (should be a data.frame) o remove confusing `no admissible split found' warning (which simply meant that the `minsplit' wasn't met). CHANGES IN party VERSION 0.9-12 (2007-06-28) o adjust to coin 0.6-4 CHANGES IN party VERSION 0.9-11 (2007-06-11) o populate `where' slot in `mob' objects. o `mob_control' now has an `na.action' argument o cforest with replace = FALSE, fraction = ... can now deal with weights (spotted by Carolin Strobl ) o interface to LAPACK (`dgesdd' for computing a SVD) directly.

Problem spotted by Henric Nilsson . CHANGES IN party VERSION 0.9-8 (2007-01-15) o thicker median lines in boxplots CHANGES IN party VERSION 0.9-7 (2007-01-15) o fix problems with multivariate response variables (spotted by Henric Nilsson ) CHANGES IN party VERSION 0.9-6 (2006-11-28) o R-2.5.0 does not allow to change the storage.mode of factors CHANGES IN party VERSION 0.9-5 (2006-10-27) o adjusted p values computed with testtype = "MonteCarlo" did not take dimensionality of the underlying linear statistics into account. It is now ensured that _p values_ are resampled, not test statistics. o fix escape problems CHANGES IN party VERSION 0.9-4 (2006-09-15) o make sure `maxsurrogates' exceeds number of input variables o fix problems reported by valgrind CHANGES IN party VERSION 0.9-3 (2006-09-08) o don't call RNG functions in mvt (this is done in C code, once) CHANGES IN party VERSION 0.9-2 (2006-09-07) o mob() can't currently handle missing values, they are removed and a warning is given. o add `methods' and `vcd' to Depends: CHANGES IN party VERSION 0.9-0 (2006-08-31) o node_barplot() can now also draw stacked barplots. o simplify handling of ordinal variables. It is now possible to have multiple (ordinal) response variables. o some documentation updates o fix problems with NA handling for factors o make sure minsplit criterion applies in the presence of missing values. Bug spotted by Han Lee . CHANGES IN party VERSION 0.8-8 (2006-08-23) o export `varimp' (variable importance measures for cforest()) o documentation updates o add codetools checks CHANGES IN party VERSION 0.8-7 (2006-07-17) o REAL(NULL) now gives an error in C code and scores could be potentially NULL: fixed for the time being. o add `show' method for BinaryTree and RandomForest objects CHANGES IN party VERSION 0.8-6 (2006-05-22) o add some validity checks for hyper parameters o add function `varimp' for computing variable importance measures for some random forests (this is still experimental and thus not exported yet, so use `party:::varimp') CHANGES IN party VERSION 0.8-5 (2006-04-25) o all hyper parameters to `cforest' are now controlled using objects of a new class `ForestControl' which can be created using `cforest_control()'. o sampling of a fraction of the observations without replacement is now available for the `cforest' implementation of random forest. CHANGES IN party VERSION 0.8-4 (2006-04-04) o renamed argument `teststattype' to `teststat' with defaults c("quad", "max") in order to be compatible with the `coin' package, version >= 0.4-5 o use `1 - (1 - p)^k' instead of `p * k' for Bonferroni-adjustment. Node 7 for the `GlaucomaM' data is now splitted in addition (in tms). CHANGES IN party VERSION 0.8-3 (2006-03-20) o `predict' returned nonsensical results in case a tree was fitted to a multivariate response variable. Now a list with one element for each observation is returned. CHANGES IN party VERSION 0.8-2 (2006-03-01) o plotting buglets fixed: improved axis in MOB plots, correct (transparent) background on jpeg() and png() devices. CHANGES IN `party' VERSION 0.8-1 (2006-02-23) o `testtype' can be Bonferroni, MonteCarlo, Univariate and Teststatistic (instead of Raw) o removed unnecessary constraint on weights in `cforest' o maximize raw test statistics for random forest by default. CHANGES IN `party' VERSION 0.8-0 (2006-02-15) o `cforest', an implementation of Breiman's random forest ensemble algorithm based on conditional inference trees (`ctree') has been added. It is somewhat experimental and thus for advanced users only. o `mob', an object-oriented implementation of a recently suggested algorithm for model-based recursive partitioning (Zeileis, Hothorn, Hornik, 2005) has been added. It works out of the box for partitioning (generalized) linear regression models, others can be easily plugged in. A new vignette "MOB" describes the implementation ideas and provides a few examples. o new S3 generic reweight() with methods for (g)linearModel for re-fitting a model with different weights. o new argument `maxdepth' to `ctree_control' which allows for growing trees of a fixed maximum depth. o LazyData: yes CHANGES IN `party' VERSION 0.3-6 (2006-02-06) o use a different way to deal with NAMESPACEs during in tests/*.R following a suggestion by Prof. Brian D.
