manymome 0.1.14

CRAN release: 2024-02-16

New Features

  • The standardizers (scale_x and scale_y) for each bootstrap or simulated sample are now stored, such that the confidence interval of the unstandardized effect can be computed even if standardization is requested. (

Bug Fixes

  • Fixed a nonessential bug with the math operator: indirect_raw, though not used for now, is now computed correctly when using + and -. (
  • Fixed a minor typo in documentation. (
  • Fixed a minor issue with the print method of delta_med-class object. (
  • Fixed a bug with using do_mc() on a model which do not have a mean structure, has latent variables, and is estimated by multiple imputation. Error is no longer raised. (
  • Fixed a few more tests that should not be run if suggested packages are not installed. (
  • No longer raises an error for dichotomous moderators. (

manymome 0.1.13

CRAN release: 2023-10-06

New Features

  • Added delta_med() for computing ΔMed (Delta_Med), an R2-like measure of indirect effect proposed by Liu, Yuan, and Li (2023). Can form nonparametric bootstrap confidence interval for ΔMed. (,
  • Added support for paths with both latent and observed variables. (,


  • Updated references. (0.1.13)

manymome 0.1.12

CRAN release: 2023-08-21

New Features

Can report standard errors (if requested)

  • All major print methods of effects support printing standard errors (setting se = TRUE). They are simply the standard deviations of the bootstrap estimates (if bootstrap confidence intervals are requested) or simulated estimates (if Monte Carlo confidence intervals are requested). They should be interpreted with cautions because the sampling distribution of the effect estimates may not be symmetric. (


  • Customized linters. (

  • Revised a test to accommodate a behavior of MKL when MASS::mvrnorm() is used to generate pseudo random numbers. (

  • Finalized to 0.1.12. (0.1.12)

Bug Fixes

  • P-value were not computed when mathematical operations are conducted on effects using + and - before version This has been fixed. (

  • merge_model_matrix() failed if all variables in an lm() output is already present in merged outputs. Fixed in (

  • cond_indirect() did not hide the progress when Monte Carlo CIs were requested and do_mc() was called internally. Fixed. It now hides the progress if progress = TRUE. (

manymome 0.1.10

CRAN release: 2023-06-08

New Features

Monte Carlo Confidence Intervals

  • Added support for Monte Carlo confidence intervals. ( to
  • Updated some vignettes for Monte Carlo confidence intervals. (
  • Please refer to this article for an illustration on forming Monte Carlo confidence interval.

Multiple Imputation

  • Added support for models fitted by runMI() or sem.mi() from the semTools package using multiple imputation. (
  • Please refer to this article for an illustration on forming Monte Carlo confidence interval.

Can report p-value (if requested)

  • Some print methods support printing asymmetric bootstrap p-values using the method presented in Asparouhov and Muthén (2021) if bootstrapping confidence interval is requested. By default, p-values are not printed. (

Report proportion of effect mediated


  • Exported get_prod() and added an article on its workflow. (
  • Bootstrapping can handle the fixed.x argument as lavaan does. (

Bug Fixes

  • Fixed factor2var() to work (again) for a categorical variable with only two levels. (


  • Updated badges in (
  • Updated pkgdown site. (
  • Used a more reliable test for Monte Carlo CIs. (
  • Updated the logo for readability. (
  • Fixed an error in pkgdown site. (
  • Added progress bars to do_mc(). (
  • Added print.mc_out(), the print-method for mc_out-class objects. (
  • Updated vignettes with package name. (
  • Fixed typos in (
  • Updated pkgdown GitHub action for using newer version of mermaid. (
  • Updated pkgdown website to use the new logo and color scheme. (
  • Modified more tests to accommodate a change in lavaan on handling random seed. (
  • No change to the main code. Added a few technical appendices as pkgdown articles, accessible through the pkgdown website of the package. (
  • Updated the documentation of functions to state that they support lavaan.mi-class objects. (

manymome 0.1.9

CRAN release: 2023-01-06


  • Modified some tests to accommodate a change in lavaan on handling random seed.
  • Made some tests run faster to meet CRAN requirements.
  • Used precomputed results to speed up the building of vignettes.

manymome 0.1.6

CRAN release: 2022-11-06

New Features



Bug Fixes

  • Updated with code for installing from CRAN. (
  • Fixed a typo in (
  • Fixed tests that should be done by expect_equal on numbers rather than on characters. No change in the functions. (
  • Noted in the vignettes that some new functions are not yet on the CRAN version and available in the GitHub version. (
  • Fixed a bug in merge_model_frame(). (


  • Finalize Version 0.1.6 for CRAN.


CRAN release: 2022-09-06

  • Checked examples and vignettes to ensure parallel processing is not used. (
  • Updated the DESCRIPTION (
  • Release version for main. (


  • Release version for main. (
  • Fixed an invalid link in (


  • Cleaned up the doc and code.


  • First public release.
