This #rstats #package #negligible examine negligible effect / #equivalent testing in #SEM model after #lavaan, a few of the functions include
1) #neg.semfit (CFI, RMSEA, SRMR)
2) #neg.normal

I want to highlight a cool website by Hermine Maes: hermine-maes.squarespace.com. She has shared code for many models used in #StatisticalGenetics.
Thank you for reading my (short) overview of SEM and how to learn it - please ask away & let me know about your experience with #lavaan or #OpenMx π
To get started in #lavaan we just take a path diagram and write out the relationships between the variables, see here:
lavaan.ugent.be/tutorial/sem...
A neat #Rpackage for visualizing results in lavaan is semPlot, also by @sachaepskamp.bsky.social. It can be used to visualize models and results.
To get started with SEM, I've watched a few videos by @sachaepskamp.bsky.social, who made his teaching materials available: www.youtube.com/@Sacha_Epska...
Like in a regression, we can write the relationships between variables using formulas. In R, we can easily do this using the #lavaan package π¦
Lovely first day of the #rainbowR conference with a trivia quiz and social by @libbyheeren.bsky.social and @damiepak.bsky.social π₯°π
Planning to finally post about #SEM tomorrow. If you have questions about working with SEM or you use #lavaan or #OpenMx please let me know in the comments! #RStats

My question. Is it possible to use #rstats #package #lavaan to asses measurement model #convergent and #discriminant #validity, then move on to #blavaan to finalize both #measurement and #structural models. I like that #blavaan has #prior() function. Need help. This is really new for me. Thanks.
#Ξ©nyx is a free #SEM app which can estimate #Latent #Change #Score #LCS model. User can even export its path diagrams to #rstats #package #lavaan. Hereβs the tutorial www.sciencedirect.com/science/arti... onyx-sem.com
Letβs say you just starting to use #rstats #SEM #package #lavaan and gotten a nice results. Next is to do a nice SEM figure, here is a #shinyapps option solo-fsw.shinyapps.io/lavaangui/ and the article www.tandfonline.com/doi/full/10....

Thoughts: This is built-in to lavaan but useful to know it exists, especially when validating and pre-reg models.

Do you do Structural Equation Modeling in #rstats? The main developer of one of the primary packages, #lavaan, is running into trouble securing funding to keep the package going, and has reached out to the community to help support. Donate here:...
Erm, #lavaan help plz.
Using MLR for several models and one model's 90% CI for the robust RMSEA is 0-0, which doesn't include the point estimate (.068)....
#Rstats
Had me w first sentence:
"No survey ever attains 100% response."π
More importantly:
ML CFA estimation w pairwise correlation for ordinal data under #MissingAtRandom in #lavaan: "acceptable relative bias & close to zero raw bias"
