In stdmod: Standardized Moderation Effect and Its Confidence Interval

stdmod 0.2.11

Miscellaneous

• Updated tests for testthat 3rd Edition. (0.2.10.2)

Bug Fixes

• In plotmod(), labels regarding SDs will no longer be displayed when w_values is set. (0.2.10.1)

stdmod 0.2.10

New Features

• Improved the printout of the summary() of std_selected() and std_selected_boot() outputs. It now prints the R-squared increase of the highest order term, as well as the F test for the increase, if the model has one and only one highest order term (e.g., an interaction term). (0.2.9.1)

• Added the argument w_values to cond_effect() and plolmod(). Users can specify the values of the moderator (w) to be used to compute the conditional effects. (0.2.9.2)

Miscellaneous

• Revised update.std_selected(). Though still not recommended, it should now work more reliably if it needs to be called. (0.2.9.1)

stdmod 0.2.9

• Fixed the issue with stdmod-package. (0.2.8.9001)
• Improved the printout of the summary() of std_selected() and std_selected_boot() outputs. Small numbers are rounded to prevent the use of scientific notation, and small p-values can be printed in formats like p<.001. Users can also control the number of digits in the printout. See the help page of print.summary.std_selected() to learn more about new arguments (0.2.8.9002).
• Finalized to 0.2.9. (0.2.9)

stdmod 0.2.8

• Added an R CMD check for noSuggests. (0.2.7.1)
• Removed dplyr from the tests and Suggests. (0.2.7.2)
• The tests using visreg will be skipped if visreg is not installed. (0.2.7.3)
• Add a note in the printout of a cond_effect-class object and the summary of a std_selected-class object. If one or more variables are standardized but bootstrapping is not requested, users will be recommended to use std_selected_boot(). (0.2.7.4)
• stdmod_lavaan() switched to the bootstrapping algorithm used by lavaan(). It also updated to allow for partial standardization. To use the older algorithm, set use_old_version() to TRUE. (0.2.7.5)
• Finalized to 0.2.8. (0.2.8)

stdmod 0.2.7

• Updated pkgdown site to bootstrap 5. (0.2.6.1)
• Fixed a missing whitepace in the note of the print() method of the summary() output of std_selected(). (0.2.6.2)
• Added to_standardize to std_selected() and std_selected_boot(). (0.2.6.3)
• Fixed a bug with confint.std_selected() when type = "lm" and bootstrapping is requested. Should not be an issue because t-based CIs should not be used when bootstrapping is requested. This option is just for testing. (0.2.6.4)
• Updated examples to use to_standardize or mention it as a shortcut. (0.2.6.5)
• Updated vignettes to introduce to_standardize. (0.2.6.6)
• Fixed a link in a vignette. (0.2.6.7)
• Finalized to 0.2.7. (0.2.7)

stdmod 0.2.6

• Improved the printout of the summary() of std_selected() and std_selected_boot() outputs. (0.2.4.9001).
• Fixed deprecated functions and arguments in ggplot2. (0.2.4.9002)
• Fixed a problem with wrapping long lines in the printout of the summary() of std_selected(). (0.2.4.9003)
• Update GitHub actions.
• Fixed a missing link in an Rd file in old macOS machines. (0.2.6)
• Use bibentry() in CITATION. (0.2.6)

stdmod 0.2.4

• Fixed a bug in std_selected(): It now works correctly when a variable in the data frame is a factor. (0.2.0.1)
• Added confint() and coef() methods for cond_effect-class objects. confint() can return confidence intervals based on t statistics, which are appropriate in some situations. (0.2.2)
• print() method for cond_effect-class objects can print confidence intervals based on t statistics. (0.2.2)
• Added do_boot to std_selected_boot(). If set to FALSE, it will not do bootstrapping. (0.2.3)
• cond_effect_boot() will disable bootstrapping in the original call if the output is generated by std_selected_boot(), to avoid redundant bootstrapping inside bootstrapping. (0.2.3)
• Added do_boot to cond_effect_boot(). If set to FALSE, it will not do bootstrapping. (0.2.4)

stdmod 0.2.0.0

• Changed the default of confint() and vcov() for std_selected-class object. If bootstrap CIs are requested, then bootstrap CIs and VCOV based on bootstrapping should be returned. (0.2.0.0)

stdmod 0.1.7.7

• Updated references. (0.1.7.5)
• Minor changes due to Roxygen updates. (0.1.7.5)
• Added R CMD Check action (0.1.7.6)
• Minor changes due to Roxygen updates. (0.1.7.7)
• Fixed a typo in CITATION

stdmod 0.1.7.4

(All major changes after 0.1.7.1)

• Fixed a bug in plotmod(). It now correctly handles more than two levels when w_method is set to"percentile". (0.1.7.2, 0.1.7.3)
• Fixed a typo in DESCRIPTION. (0.1.7.4)

stdmod 0.1.7.1

(All major changes after 0.1.5)

• Added plotmod() for plotting moderation effects. This function will check whether a variable is standardized. If yes, will note this in the plot.
• plotmod() can also plot a Tumble graph (Bodner, 2016) if graph_type is set to "tumble".
• Updated vignettes to use plotmod() instead of visreg::visreg().
• Added cond_effect() for computing conditional effects. This function will check which variable(s) is/are standardized. If yes, will note this in the printout.
• Added cond_effect_boot(), a wrapper of cond_effect() that can form nonparametric bootstrap confidence intervals for the conditional effects, which may be partially or completely standardized.
• Updated the print method for the summary of std_selected() and std_selected_boot().
• Added more vignettes to introduce the new functions.
• stdmod_lavaan() now returns an object of the class stdmod_lavaan, with methods print, confint, and coef added.

stdmod 0.1.5

• Changed the column order of the coefficient table in std_selected_boot() output. Bootstrap confidence intervals are placed next to parameter estimates.
• Added vcov() method for std_selected() output. If bootstrapping is used, it can return the variance-covariance matrix of the bootstrap estimates.
• Added confint() method for std_selected() output. If bootstrapping is used, it can return the bootstrap percentile confidence intervals if requested.
• Other minor fixes.

stdmod 0.1.3

• Set up gh-pages and fix dependency in vignette.

stdmod 0.1.2

• Updated the methods for std_selected().

stdmod 0.1.1

• The first version.
