This reproducible R Markdown analysis was created with workflowr (version 1.4.0). The Checks tab describes the reproducibility checks that were applied when the results were created. The Past versions tab lists the development history.
The R Markdown is untracked by Git. To know which version of the R Markdown file created these results, you’ll want to first commit it to the Git repo. If you’re still working on the analysis, you can ignore this warning. When you’re finished, you can run wflow_publish
to commit the R Markdown file and build the HTML.
Great! You are using Git for version control. Tracking code development and connecting the code version to the results is critical for reproducibility. The version displayed above was the version of the Git repository at the time these results were generated.
Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish
or wflow_git_commit
). workflowr only checks the R Markdown file, but you know if there are other scripts or data files that it depends on. Below is the status of the Git repository when the results were generated:
Ignored files:
Ignored: .RData
Ignored: .RDataTmp
Ignored: .Rhistory
Ignored: .Rproj.user/
Untracked files:
Untracked: analysis/est_ulsmv.Rmd
Untracked: analysis/est_wlsmv.Rmd
Unstaged changes:
Modified: analysis/est_mlr.Rmd
Modified: analysis/fit_boxplots.Rmd
Modified: analysis/index.Rmd
Modified: analysis/index_cfi.Rmd
Modified: analysis/index_rmsea.Rmd
Modified: analysis/index_srmr.Rmd
Modified: analysis/index_tli.Rmd
Modified: analysis/roc_analyses.Rmd
Note that any generated files, e.g. HTML, png, CSS, etc., are not included in this status report because it is ok for generated content to have uncommitted changes.
There are no past versions. Publish this analysis with wflow_publish()
to start tracking its development.
MUCH TO ADD HERE (NOT FINISHED)
The WLSMV fit function has been shown to be:
\[F_{WLSMV}= {\left(s - \sigma(\hat\theta)\right)}^{\prime}W^{-1}{\left(s - \sigma(\hat\theta)\right)}\]
where the interested reader is refered to Muthen (1978) for information on the WLS estimation method more generally, and Muthen (1994) for the general ML-CFA model formulation but to (include references to two-level estimation with WLSMV).
WLSMV takes significantly longer than MLR (i.e., WLSMV was 2-5 minutes per replication compared to MLR which converged in no more than a second or two).
