In brandmaier/semtree: Recursive Partitioning for Structural Equation Models

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
• prefer semforest_control() over semforest.control() and semtree_control() over semtree.control()
• added heuristics for choosing mtry in forests (if NULL) and for choosing min.N and min.bucket (if NULL)
• moved dependency on ctsemOMX to suggested package

semtree 0.9.19 (2023)

• 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)

• 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)

• 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)

• 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)

• 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)

• bugfix in invariance testing
• fix to remove warning from rpart plot (version 3.0.0 and above)

semtree 0.9.12 (2018)

• 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)

• 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)

• 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
