CHANGES IN party VERSION 0.9-999 (2009-09-24) o minbucket was erronously interpreted as minbucket + 1 o p-values for teststat = "max" were wrong in the uncommon case of zero variances CHANGES IN party VERSION 0.9-998 (2009-06-17) o mtry may vary with tree depth o finding surrogate variables may have failed, fixed. CHANGES IN party VERSION 0.9-997 (2009-06-04) o documentation fixes CHANGES IN party VERSION 0.9-996 (2009-03-27) o survival fixes CHANGES IN party VERSION 0.9-994 (2009-02-10) o fix bug in new varimp function (which was triggered by splits in categorical variables) CHANGES IN party VERSION 0.9-993 (2009-01-29) o new C-level function R_remove_weights CHANGES IN party VERSION 0.9-992 (2009-01-19) o update CITATION file CHANGES IN party VERSION 0.9-991 (2009-01-13) o new conditional variable importance measure (Strobl et al., 2008, BMC Bioinformatics) available. 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. Spotted by Sebastian Wietzke CHANGES IN party VERSION 0.9-97 (2008-06-26) o predictions for new data containing missing values were wrong.

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. As a side-effect, the svdmem class can be simplified and no memory allocation during tree growing is necessary (which results in a measureable performance gain) CHANGES IN party VERSION 0.9-10 (2007-02-28) o internal infrastructure for fit(x, y) interfaces, including a VariableFrame method for matrices. o deal with factors with only one level and variables where all observations are NA o don't compute design matrices in `ModelEnvFormula' CHANGES IN party VERSION 0.9-9 (2007-02-02) o internal changes to data objects: joint transformations only necessary for response variables (new class `ResponseFrame') but we need to distinguish between testing (using ranks, for example) and prediction (means of raw data!). 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. Ripley o use LazyLoad: yes instead of SaveImage: yes CHANGES IN `party' VERSION 0.3-5 (2006-02-02) o make R CMD check happy and move src/README to inst/README CHANGES IN `party' VERSION 0.3-4 (2006-01-18) o documentation updates CHANGES IN `party' VERSION 0.3-3 (2006-01-18) o some new convenience functions, not exported CHANGES IN `party' VERSION 0.3-2 (2006-01-12) o isequal must not check equality of attributes CHANGES IN `party' VERSION 0.3-1 (2005-12-02) o fix bug introduced in version 0.3-0: coin:::factor_trafo applies treatment contrasts in case of a binary factor but we need the full design matrix o documentation updates CHANGES IN `party' VERSION 0.3-0 (2005-11-29) o `ytrafo' and `xtrafo' functions make use of `coin:::trafo' now, i.e. the handling of influence functions and transformations has been unified in packages `party' and `coin' CHANGES IN `party' VERSION 0.2-10 (2005-11-08) o new slot `data' in BinaryTree objects, slots inputnames and levels have been removed CHANGES IN `party' VERSION 0.2-9 (2005-10-19) o splits in categorical variables could have failed due to weired internal checks CHANGES IN `party' VERSION 0.2-8 (2005-08-06) o fix problems reported by codetools CHANGES IN `party' VERSION 0.2-7 (2005-08-31) o extract inputs using menv@get("input", data = newdata) in predict CHANGES IN `party' VERSION 0.2-6 (2005-08-29) o make gfortran happy CHANGES IN `party' VERSION 0.2-5 (2005-08-19) o ctree() now searches the global environment for variables given in `formula' when the `data' argument is unspecified. CHANGES IN `party' VERSION 0.2-4 (2005-07-07) o names of `criterion' element in `SplittingNode' objects were wrong o categorical splits with `ctree_control(testtype = "MonteCarlo")' were potentially wrong CHANGES IN `party' VERSION 0.2-3 (2005-06-29) o print and plot only levels which are available in a node (for nominal splits) CHANGES IN `party' VERSION 0.2-2 (2005-06-27) o ./src/Makedeps will be automatically generated (on Windows) and must not be part of the source-package. o vignette cosmetics
