Where is the Script for Path analysis in R?

[ThimaliFernando]

Thank you very much! A quick question. Aren't we supposed to check model assumptions like we do after fitting a regression model? Or is it enough to look at only fit indices CFI, TLI, chi square, RMSEA and SRMR?

[evahormann]

Thank you for the great video!
I`m new with R and I do not understand how you could interpret the significance levels or the correlations between the variables from the output. Could you please explain this?

THANKS FOR NICE VEDIO. How did you handle variables such as priming, water and rep in your analysis, I mean did you consider those as well. Please help me as my problem is something similar . Advance thanks

Hi, thank you for this lecture. I would like to ask how to go about a case where I have two IV and two moderators. I think the model specification will be modelspec <- "DV~IV1+IV2+IV1*moderator1 + IV1*moderator2+IV2*moderator1 + IV2*moderator2"? I used this logic but did not get the result of the path for the effect of the two moderators on one of the IVs. I would appreciate it if you have any idea about how to go about this. Thanks.

in model estimation step the output is like this
mod.est = sem(model = mod.id,
+ data = data)

Error in if ((!is.matrix(model)) | ncol(model) != 3) stop("model argument must be a 3-column matrix") :
argument is of length zero

how to rectify this sir

When i calculate vaeiability through R Studio, the result shows negative values in fcal. Please suggest me your opinion and let me know if there is any corrections

[icefunkdark]

There is a small mistake "data$rep = as.factor(data_corr$priming)” is incorrect. it should be priming on the left side too

[samanthamccann]

I can never find the function fit.measures, only fitmeasures or fitMeasures, do you know why this is?

Thanks dear for a good video about path analysis

[Satoshi]

The dada importing process does not work. I cannot access the data I. literally tried everything but I cannot load a data file data_path.xls which I have not downloaded beforehand.

[shahfahadalishah]

So interesting and knowledgeable for me.
Sir in another also includes fixed effect and random effect sem model. Thanks

[GUGU]

Very informative. Would you please like to share the code and dataset.

[mohsinaanjum]

Thank you can u please make a tutorial video on redundancy analysis

[asadalisarkar]

Please Prepared SEM with Likert scale based data

[Sunny-China]

Please make video on DDRs, distance decay relationship plot. Will be very appreciated.
