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

CRAN release: 2023-09-11

  • 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

CRAN release: 2023-06-24

  • 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

CRAN release: 2023-03-26

  • 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

CRAN release: 2023-03-10

  • 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

CRAN release: 2022-09-21

  • 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

CRAN release: 2022-08-07

(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

CRAN release: 2022-05-11

(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

stdmod 0.1.1

  • The first version.
