semtree 0.9.20 (2024)
added an error handler for score-based tests when the vcov matrix cannot be computed (e.g., models with Heywood cases)
leaner package imports: removed dependency on bitops and stringr package
semtree 0.9.19 (2023)
2023-11-26
changed default behavior of print function of varimp, such that na.omit=TRUE, which is consistent with other packages like party or partykit
fixed issues with toTable()-command, by default, all parameters are shown now, also fixed a bug with score-based tests and toTable()
fixed problem with focus-parameters and variable importance
bugfix in score-based tests that sometimes did not respect min.N constraints
new functionality for parameter contribution evaluation
more verbose vignettes
removed dependency on set, plotrix and digest package to make package imports leaner
semtree 0.9.18 (2022)
2022-05-13
happily welcoming Caspar van Lissa to the developer team
more efficient implementation of partial dependence and proximity
new predict() functions
bugfix in handling factors with non-numeric levels
removed crossvalidation splitting after deprecation in v0.9.15
exporting strip() function for lighter SEM trees in forests
introducing new classed tree_stripped and forest_stripped
semtree 0.9.16 (2021)
2021-06-11
removed all code based on parallel-package and replace by future-equivalent. Thanks to Michael Krause!
restored semtree.print() generic function that was accidentally dropped in 0.9.15
fix to score-based tests to support definition variables in OpenMx. Thanks to Manuel Arnold!
semtree 0.9.15 (2021)
2021-04-28
roll-out of score-based tests - use method “score” to enable
use of method “cross-validation” is now deprecated and discouraged
added variable importance for focus parameters
added new vignettes
fixed compatibility with new OpenMx version
semtree 0.9.14 (2020)
2020-01-07
added requirement rpart.plot > 3.0.6 to avoid error w.r.t. to missing round.int
Manuel Arnold joined the team to work on a score-test implementation
fixed behavior of min.N in semtree.control()
semtree captions uses signif for truncating decision thresholds to three significant digits
fixed class type checks to be compatible with upcoming R 4.0.0
semtree 0.9.13 (2018)
2018-11-05
bugfix in invariance testing
fix to remove warning from rpart plot (version 3.0.0 and above)
semtree 0.9.12 (2018)
2018-02-13
bugfix in split evaluation procedure for cases where variables are named ‘c’, which crashed semtree
bugfix in varimpConvergencePlot: na.omit command logic was inverted
semtree 0.9.11 (2017)
2017-12-14
semforests support for lavaan models including variable importance and partial dependence
crossvalidated likelihood supported with lavaan
plots of semtrees show correct #df when using focus parameters
added diversity functions
semtree 0.9.10 (2017)
2017-04-05
added NEWS.md file
bugfix to partial dependence on variables of type factor
bugfixes to plotting of partial dependence
deprecated partialDependencePlot and introduced partialDependence() function with S3 plotting method
added parallel computation option to partialDependence
added new demo scripts
added extra.legend parameter to varimpConvergencePlot
bugfix in traverse() that led to underestimations of variable importance in some cases
added error message when trying to use lavaan and global constraints
