FIML estimation of multiple missing covariates in a three-level meta-analysis
Dear fellow researchers,
I am currently writing my PhD thesis in psychology. Part of my thesis is a **three-level meta-analysis** of the relationship between personality (i.e. conscientiousness) and self-efficacy in school students (in primary and secondary education).

Problem with plotting using semPaths
Dear professor Cheung,
I am running into a problem with plotting my model. I have included the replicated data, and my script. My error is that:
Error in if (Layout[x[1], 2] != Layout[x[2], 2]) return(0) else return(sum(Layout[Layout[, :
missing value where TRUE/FALSE needed
I’ve tried to search this error online, but I did not prevail. I hope you can take a quick peek and help me with this problem. I’d really appreciate your time.
Sincerely,
Mike

Testing interaction effects in TSSEM
Dear Mike,
Thanks for being so helpful in previous instances that we've had a question about metaSEM. metaSEM has made it possible for us to conduct meta-analysis beyond anything we envisioned was possible 5 years ago.
We would like to test whether the exogenous variables in our model interact with each other with respect to each endogenous variable in our model.
There are four exogenous variables: UNIres, TTOres, REGres, and uSize
There are also four endogenous variables: LicRev, LicNum, Spin, and Perf

OpenMX status1: 5 and SEs of estimates?
Hi there. I'm using `metaSEM::meta()` to conduct some single-level meta-analyses.
In some subset analyses, as *k* gets smaller, OpenMX seems to struggle to estimate the variance, estimating Tau2 as low as I will set `RE.lbound`. I can resolve the error message by running a fixed-effects model by setting `RE.constraint = 0`. However, when I do this, the standard error for the intercept increases by 33%. This changes the statistical significance of the intercept.

Saturated Model and Non positive - OSMASEM
Dear Cheung,
First of all, thank you for your helpful and inspiring contribution. We are very grateful for your interesting work and now we are trying to follow your steps and conduct a meta-analysis. However, on the way, we have had some doubts that we wanted to share with you as we are looking for some advice.

rerun() pastes the steps in R Markdown
Dear Cheung,
Congratulate on the great work done in the field of SEM and METASEM. Your contributions are very useful for the scientific and educational community.
I am using the rerun() function in markdown, to avoid pasting the steps of this function in the document I try to include some parameters of other functions that use functions that rerun uses. For example, silent = False from mxRun (). Any idea how to solve it?
Thank you for your attention,

Mediation Model
Hello all,
I am trying to fit a mediation model where each of my main variables (BS, IND, WOB, DUA, BMEET and DIROWN) is mediated by another variable(BNKRISK). I have been following the model following Cheung (2021): Synthesizing Indirect Effects in Mediation Models with Meta-Analytic Methods: Supplementary Materials 2. I will proceed sequentially using to help you to follow the steps and where I encountered the error. This the model is

Error in tssem2
Hi Cheung,
I want to test a higher order CFA model by metaSEM, but i have only item correlations. In your book, a higher order model of Big Five model has been included. When i examined this example, i realised that i need the correlations between factors.
