NEWS file for the tram package

Changes in Version 0.4-0 (2020-05-11)

• Add Aareg for Aalen additive hazard models.

Changes in Version 0.3-3 (2020-01-16)

• score_test generic and method added for computing score tests and corresponding confidence intervals.

• perm_test generic and method added for computing permutation score tests.

• PI converts log-odds ratios to probabilistic indices and vice versa.

Changes in Version 0.3-2 (2020-01-08)

• profile method added for computing profile likelihood confidence intervals.

• Allow additional linear inequality constraints for regression coefficients.

Changes in Version 0.3-1 (2019-11-05)

Bugfixes

• Fix problem in C header file.

• Fix problems with responses of class R, spotted by Balint Tamasi.

Changes in Version 0.3-2 (2019-12-02)

• Add new demo.

Bugfixes

• Deal with model_only in Survreg, spotted by Balint Tamasi.

Changes in Version 0.3-0 (2019-10-09)

Bugfixes

• y | s1:s2 ~ x lead to rank-deficit models, the intercept is now removed.

• Not really a bug, but time-consuming examples were removed (or replaced by static output) in package vignettes to make CRAN happy.

• as.mlt returned an object of class mlt but not mlt_fit.

New Features

• New marginally interpretable models for clustered data in mtram, see mtram vignette. This is still experimental and very rough, so please be careful.

• Compute vcov.tram via Schur complement when possible.

Changes in Version 0.2-6 (2019-06-20)

• Add regression test for count data and log_first = TRUE.

Changes in Version 0.2-5 (2019-02-25)

• tram objects are now in line with multcomp::glht, allowing post-hoc multiple comparisons.

Changes in Version 0.2-4 (2019-01-22)

• log_first = TRUE is now accepted by tram and all model functions calling tram. This is still experimental.

• Silence regression tests on Windows.

Changes in Version 0.2-3 (2018-09-17)

• New extrapolate = TRUE option for all models constraints the second derivate of the Bernstein transformation function to be zero at support. This helps to get rid of possible discontinuous densities at support.

• Add Lehmann for fitting shift transformation models those linear predictor can be interpreted as log-Lehmann-alternative.

• Add method = "loglog" to Polr.

• New update method.

Changes in Version 0.2-2 (2018-06-22)

• Use default bounds = c(0, Inf) for Surv objects (for example in Coxph.

• Update to mlt 1.0-2.

Changes in Version 0.2-1 (2018-04-20)

• Likelihood ratio tests with fixed parameters gave an error.

• Remove strata from linear predictor (experimental).

• Try to implement a better guess for the add argument later defining the axes corresponding to the response in plots.

• All models accept add and bounds arguments.

Changes in Version 0.2-0 (2018-02-25)

• tram first published on CRAN.
