In semfindr: Influential Cases in Structural Equation Modeling

semfindr 0.1.9

Improvement

• Updated user_change_raw() to allow for user functions that return an unnamed vector. Also added a pkgdown website article for user_change_raw(). (0.1.8.5)

• For lavaan_rerun(), added the argument ncores to make it easier to set the number of CPU cores to use in parallel processing. (0.1.8.7)

• For lavaan_rerun(), added the option to show a progress bar (generated by pbapply) by setting progress to TRUE. Enabled by default. (0.1.8.8)

Miscellaneous

• Added on.exit() such that workers will be stopped if lavaan_rerun() terminates abnormally. (0.1.8.2)

• Updated some default values of approx_check() to reflect new features added to other functions. (0.1.8.4)

• Fixed a few Rd issues on CRAN. (0.l.8.6)

• Print a more conservative estimate of the expected time. (0.1.8.7)

• Remove an invalid link in the reference. (0.1.8.9)

Bug Fixes

• Fixed a bug with index_plot() when the extracted column has no names. (0.1.8.1)

semfindr 0.1.8

Others

• Updated the two tests for nonconvergence. Will check against results generated by directly calling lavaan functions. (0.1.6.1)

Bug Fixes

• Fixed a bug with listwise deletion in lavaan_rerun(). (0.1.6.2)

semfindr 0.1.6

New Features

• Added index_plot() for generating an index plot for an arbitrary statistic. (0.1.5.5)

• Added user_change_raw() for computing case influence on user statistics. (0.1.5.8)

Others

• Fixed typos in the article on multiple-group models. (0.1.5.1)

• Fixed an error at CRAN check due to suggested packages not installed. (0.1.5.3)
• Use lavaan::lavCor() to estimate means and correlations for Mahalanobis distance when missing data is present. The package norm2 is no longer needed nor suggested. (0.1.5.4)

• Updated README.md. (0.1.5.7)
• Finalized 0.1.6. (0.1.6)

semfindr 0.1.5

New Features

• Added a print method for the output of est_change(), est_change_raw(), est_change_approx(), and est_change_raw_approx(). (0.1.4.3, 0.1.4.16, 0.1.4.18, 0.1.4.19, 0.1.4.20)
• Added a print method for the output of fit_measures_change() and fit_measures_change_approx(). (0.1.4.4, 0.1.4.16)
• Added a print method for the output of mahalanobis_rerun() and mahalanobis_predictors() (0.1.4.5-0.1.4.6, 0.1.4.16, 0.1.4.18)
• Added a print method for the output of influence_stat(). (0.1.4.7)
• Provided initial support for multiple-group models and models with linearity constraints. (0.1.4.8 - 0.1.4.14)
• Added support for labels and ":=" to pars_id(). (0.1.4.13)

Others

• Fixed the pkgdown site. (0.1.4.1)
• approx_check() will check if the model has at least one equality constraint. (0.1.4.2)
• Added a "Limitations" section to the vignette of the approximate approach. (0.1.4.2)
• Fixed the documentation of pars_id(). (0.1.4.12)
• Added an article for multiple-group models. (0.1.4.15)
• Restructured articles and references in the pgkdown websites. (0.1.4.15)
• In print.lavaan_rerun(), keep the format of lavaan warnings. (0.1.4.17)
• Remark that fit_measures_change_approx() only supports selected fit measures. (0.1.4.21)
• Add cutoff_change and largest_change to est_change_gcd_plot(). (0.1.4.22)
• Updated a few tests on parameters which are fixed in the model but their standardized versions are free. (0.1.4.23)
• Updated vignettes and articles with links to the package website. (0.1.4.24)
• Updated all vignettes for the new print methods. (0.1.4.25)

semfindr 0.1.4

• Added DOI of Pek and MacCallum in the DESCRIPTION. (0.1.1.1)
• Added approx_check() to check whether the input object is supported by the approximate method. (0.1.1.2)
• Added est_change_plot() and est_change_gcd_plot(), diagnostic plots for casewise influence on parameter estimates. (0.1.1.3)
• Diagnostic plot functions revised to allow users to fully control elements drawn. (0.1.1.4)
• Fixed typos and grammatical mistakes in help pages and vignettes. (0.1.1.5)
• Fixed an invalid URI in a vignette (casewise_scores). (0.1.3)
• Added the documentation for the return value of pars_id_to_lorg(). (0.1.4)

semfindr 0.1.1

• First public release.
• Added skip_all_checks to lavaan_rerun(), allowing users to experiment lavaan_rerun() and other functions on models not officially supported.
• Revised est_change() and est_change_raw() to support the use of operators (e.g., ~, =~) to select parameters.
• Added badges and R CMD Check Action.
• Updated est_change(), est_change_raw() and est_change_approx() to support models with labelled parameters. (0.1.0.9005)
• Added pars_id() and pars_id_to_lorg() for converting parameter specification to identification numbers ( positions in the vector of coefficients or row numbers in the parameter tables). (0.1.0.9006)
• Updated est_change_* functions to use pars_id() and pars_id_to_lorg(). (0.1.0.9007)
• Modified lavaan_rerun() to use lavaan::lavaan() instead of update() as the default way to rerun. (0.1.0.9008).
• Updated some of the tests. (0.1.0.9009)
• Added more examples. (0.1.0.9010)
• Updated documentation (e.g., README and DESCRIPTION). (0.1.0.9011)
• Updated influence_stat() and the plot functions to support the approximate approach. (0.1.0.9012)
• Updated documentation.

semfindr 0.1.0

• Added more vignettes.

• lavaan_rerun() can accept an output with inadmissible estimates. Disabled by default. Can be enabled by setting allow_inadmissible to TRUE.

semfindr 0.0.4

• Added a print method for the lavaan_rerun() class.

• Added mahalanobis_predictors() to compute the Mahalanobis distance using only the observed predictors.

• Both mahalanobis_predictors() and mahalanobis_rerun() support datasets with missing data.

• lavaan_rerun() can specify cases to exclude and rerun by specifying the case IDs or selecting cases based on Mahalanobis distance on all observed variables or on residuals of observed variables in a path model.

semfindr 0.0.3

• Used lavaan::update() in lavaan_rerun. This is more reliable than recreating the call.

• Added implied_scores(). It supports only single-group path analysis models for now.

semfindr 0.0.2

• First internal testing release.
