manymome 0.1.14.16

New Features

  • Many functions have been updated to work for multigroup models fitted by lavaan. Most common tasks are supported. There likely are functions that may not yet work on multigroup models. Checks will be added to them to alert users. For now, only some functions (e.g., cond_indirect_effect()) supports multigroup models which have one or more moderators within each group, but these models are rare. Functions that do not yet support multigroup models (e.g, mod_levels()) will raise an error if used on a multigroup model. (0.1.14.2 to 0.1.14.5, 0.1.14.12 - 0.1.14.13)

  • Relaxed the requirement that only different paths can be used in + and -. They can now be used in these operations, as they may be paths in different groups in multigroup models. (0.1.14.2)

  • The plot-method of cond_indirect_effects-class objects will be forced to be a tumble graph if the lines for different groups are to be plotted. In these cases, the data within each group will be used, including standardization. This approach, though leading to results different from those in single-group model using the group as a moderator, makes more sense for multigroup models, in which the distribution of variables are allowed to be different between groups. Since 0.1.14.10, by default, the model implied statistics are used to determine the means and SDs used in drawing he plot. This approach is useful when equality constraints are present. (0.1.14.2, 0.1.14.6, 0.1.14.10, 0.1.14.11)

  • The plot-method of cond_indirect_effects-class objects now supports plotting a path that involves latent variables. The model implied statistics will always be used for the latent variables when determining the means and SDs. (0.1.14.7)

  • Added plot_effect_vs_w(). It can plot an effect (direct or indirect) against a moderator, using the output of cond_indirect_effects(). (0.1.14.14 - 0.1.14.15)

  • Added pseudo_johnson_neyman(). It used the pseudo Johnson-Neyman approach (Hayes, 2022) to find the value of a moderator at which the conditional effect (direct or indirect) changes from nonsignificant to significant (or vice versa), based on the confidence interval selected. (0.1.14.16)

Miscellaneous

  • If a dataset has a variable which is a product of itself and another variable (e.g., x*y == x), find_products() will be trapped in an infinite loop. This “product term” will no longer be treated as a “product term.” (0.1.14.1)

  • Bootstrapping and Monte Carlo simulation will no longer be run once for each path in many_indirect_effects(). If do_boot() or do_mc() is not used first but bootstrapping or Monte Carlo confidence intervals are requested, this process will be done only once, and the estimates will be reused by all paths. (0.1.14.9)

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. (0.1.13.2)

Bug Fixes

  • Fixed a nonessential bug with the math operator: indirect_raw, though not used for now, is now computed correctly when using + and -. (0.1.13.1)
  • Fixed a minor typo in documentation. (0.1.13.3)
  • Fixed a minor issue with the print method of delta_med-class object. (0.1.13.4)
  • 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. (0.1.13.5)
  • Fixed a few more tests that should not be run if suggested packages are not installed. (0.1.13.6)
  • No longer raises an error for dichotomous moderators. (0.1.13.7)

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. (0.1.12.1, 0.1.12.3)
  • Added support for paths with both latent and observed variables. (0.1.12.2, 0.1.12.4)

Miscellaneous

  • 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. (0.1.11.2)

Miscellaneous

  • Customized linters. (0.1.11.1)

  • Revised a test to accommodate a behavior of MKL when MASS::mvrnorm() is used to generate pseudo random numbers. (0.1.11.4)

  • 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 0.1.11.2. This has been fixed. (0.1.11.2)

  • merge_model_matrix() failed if all variables in an lm() output is already present in merged outputs. Fixed in 0.1.11.3. (0.1.11.3)

  • 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. (0.1.11.5)

manymome 0.1.10

CRAN release: 2023-06-08

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. (0.1.9.7)
