Overview

About

Maintained by Shu Fai CheungCRAN page ↗GitHub ↗Website ↗Issues ↗

Computes indirect effects, conditional effects, and conditional indirect effects in a structural equation model or path model after model fitting, with no need to define any user parameters or label any paths in the model syntax, using the approach presented in Cheung and Cheung (2024) doi:10.3758/s13428-023-02224-z. Can also form bootstrap confidence intervals by doing bootstrapping only once and reusing the bootstrap estimates in all subsequent computations. Supports bootstrap confidence intervals for standardized (partially or completely) indirect effects, conditional effects, and conditional indirect effects as described in Cheung (2009) doi:10.3758/BRM.41.2.425 and Cheung, Cheung, Lau, Hui, and Vong (2022) doi:10.1037/hea0001188. Model fitting can be done by structural equation modeling using lavaan() or regression using lm().

Changes in 0.3.7

New Features

Update the q_* functions (q_mediation(), q_simple_mediation(), q_serial_mediation() and q_parallel_mediation()) to support models with moderators (moderated mediation). The paths moderated are specified by the argument moderators. Models fitted by multiple regression or structural equation modelling on observed variables only are supported. If a model has latent variables and is fitted by structural equation modeling, then the indicator_method must be set to "sam" to use the structural-after-measurement method. (0.3.6.3)

Show all changes in 0.3.7Hide the rest of the changes in 0.3.7

Updated index_of_mome() and index_of_momome() to use standard deviation as the unit of the moderator to compute the index, as proposed by Cheung and Cheung (2024), enabled by the arguments w_unit and z_unit. Also added two wrappers, z_index_mome() and z_index_of_momome(), with w_unit and z_unit set to "sd" automatically. (0.3.6.13)

Improvement

Users can specify the change of moderator values when calling index_of_mome() and index_of_momome() via the new arguments increase_from, increase_to, w_increase_from, w_increase_to, z_increase_from, and z_increase_to. (0.3.6.5)
Added the argument cond_indirect_effects_args to the q_* functions for customizing the computation of conditional indirect effects or conditional effects. (0.3.6.14)
Most confint methods now can make use of the value set to level. If not set, the default is NULL and the stored value of level (e.g., when calling indirect_effect()) will be used. (0.3.6.15)
Added the argument wlevels_not_found to cond_indirect_effects(). If a variable in wlevels is not found among the component of the product term(s), a warning will be issued by default. These variables can be ignored silently by setting wlevels_not_found to "ignore". If desired, an error can be raised by setting wlevels_not_found to "error". (0.3.6.17)
The print method of cond_indirect_effects objects (print.cond_indirect_effects()) will now print the computation formula. (0.3.6.18)

Miscellaneous

Updated some tests for the forthcoming lavaan 0.7-1. (0.3.6.1)
Fixed handling a special case: x:w:w == x. (0.3.6.2)
Updated to handle possible NA from parallel::detectCores(). (0.3.6.4)
Added pkgdown website articles on regression models with moderators (no mediators). (0.3.6.7)
Suppressed a lavaan 0.7-2 warning that does not affect the computation. (0.3.6.8)
Fixed a typo in a help page of data_mod_cat_num_2w. (0.3.6.8)
Fixed some tests to work with auto.cov.x = TRUE in lavaan (default to FALSE in lavaan 0.7-2). (0.3.6.9)
Amended some tests to allow for optimization noise. (0.3.6.10)
Stored indices of sampled cases (ids or design, if available). (0.3.6.11)
Updated many_indirect_effects() to do bootstrapping or Monte Carlo simulation only once when ci_type is set. (0.3.6.12)

Bug Fixes

Fixed a bug in finding a product term automatically in some special cases. (0.3.6.16)

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("manymome", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("sfcheung/manymome")

Development version from sfcheung/manymome. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-manymome

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-manymome

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-manymome

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
