NEWS file for the trtf package

Changes in Version 0.4-3 (2025-01-29)

• Update suggested packages.

Changes in Version 0.4-2 (2023-02-10)

• min_update is the number of observations with non-zero weight. Documentation was correct but code worked with sum(weights).

Changes in Version 0.4-1 (2022-04-07)

• Documention and test updates.

Changes in Version 0.4-0 (2022-04-05)

• New intercept argument for residual-based tree induction (shift and scale).

• Plot discrete distributions.

Changes in Version 0.3-9 (2022-01-12)

• Remove maxit argument (was ignored by mlt).

Changes in Version 0.3-8 (2021-09-03)

• Replace .R2vec by as.double method.

• Update references.

Changes in Version 0.3-7 (2020-04-22)

• Setting min\_update might have caused constant predictions.

• Update simulations / demos.

Changes in Version 0.3-6 (2019-10-03)

• Add min\_update parameter; model parameters are only updated when the number of observations in a node exceeds this number. Defaults to two times the number of parameters in the model.

• Failure to update model parameters lead to a stop in tree recursion. Following a remark by Stefan Wager, the parameters from the parent node are now used in such a case, allowing larger trees to be grown by keeping the scores constant. Note that update = FALSE triggers this behaviour in all nodes below the root node.

Changes in Version 0.3-5 (2019-02-01)

• Add R code reproducing empirical results for "Survival Forests under Test".

Changes in Version 0.3-4 (2019-01-15)

• Respect scale argument from object.

• traforest broke in extremely rare cases due to incorrect dimensions of the score matrix.

Changes in Version 0.3-3 (2018-09-18)

• All reparameterisation for max-type tests; this might give better (more powerful) variable selection.

• Allow fixed coefficients in trees and forests; this is useful for log-rank splitting, for example.

Changes in Version 0.3-2 (2018-06-22)

• Document predict and logLik methods.

• Add applyfun and cores arguments to predict method for transformation forests (allowing parallel computation of predictions.

Changes in Version 0.3-1 (2018-04-20)

• Some improvements in internal functions.

• Simulations with 500 (not 50) noise variables.

• Simplify likelihood evaluations based on new capabilities in mlt.

• New update argument for transformation forests.

• Update outputs (scale = TRUE in partykit 1.2-1).

Changes in Version 0.3-0 (2018-01-04)

• The trtf package was first published on CRAN.
