Hi, Tarandeep is absolutely right. Thank you! We do not do the normalisation, but we plan to add the option to apply it. Best, Julius

I am quite confused. Can you share your .jasp file? Have tried running all this in R? Are the results then different from JASP?

Hi, regarding question 1) What is the syntax you put in? Without it, I can't be sure what is going wrong. Question 2) What do you mean with nonlinear data? Question 3) Yes, can't handle missing data, that is, cases with missings are deleted befor…

Exactly. We have had a discussion with Klaas Sijtsma about this, and we came to the conclusion that through the standardisation differences in the variances are lost. It is true however, that we offer standardised alpha  because it is somewhat of a…

Hi, the difference stems from the psych package in R using the data correlation matrix to find the factor loadings to compute omega, and in JASP we use the covariance matrix, because we deem it more informative. Julius

Hi Carmen, you are correct, that there is a mismatch and we have already had a spirited discussion about this https://github.com/jaspstats/jaspissues/issues/2418. So far these are the eigenvalues of the correlation matrix, but in the table that is…

Hi Rama, I think without your data I cannot find out if there is something wrong with your code. It looks fine on a first glance. In any case, this seems more like a GitHub issue https://github.com/jaspstats/jaspissues/issues/new/choose. It would…

Hi kmkuo, that is a good question. So far the measures you mentioned are not implemented in JASP, but they do exist for PLSSEM and it should not be too hard to implement. I have added your request to this issue https://github.com/jaspstats/jaspi…

Hi gvt, what do you mean by "nonparametric" data? Binary data? Or ordinal data? Or data that follows no clear distribution? Julius

Hi CineSeriesly, I am not quite sure I understand. In order to help I need more information. What exactly do your two data sets look like? You have the same subjects rated by different raters but then in two data sets? Or do you just want to the s…

Hi gvt, So far you cannot get the standard error of measurement in JASP. To obtain a single value for the sem you could transform the reliability, that is, sem = sd(sum scores) * sqrt(1rel). I dont know about the confidence interval though. Julius

Hi, there is an open pullrequest for the HTMT and AVE for the SEM module https://github.com/jaspstats/jaspSem/pull/143. The CFA module already offers these. So basically, for SEM the code is there, it just needs to be reviewed and then merged and…

And given that there was this bug https://github.com/jaspstats/jaspissues/issues/2260 you might not reproduce this as the checkbox for disattenuation has no effect in the current JASP version; it is always set to TRUE.

Ah, so that was longer detective work than I anticipated, given that the issue is kind of obvious :) But in short, the issue comes from setting "disattenuate = TRUE". In your R code you have disattenuate = FALSE, which makes the code run s…

you are correct. It is quite slow in JASP. I will look into it. May I have your permission to transform this into a GitHub issue?

Hmm, I agree that JASP will likely be slower than cSEM in R given that there is a bit of overhead with any analysis. I wonder if you can quantify the difference? Or might you be able to share the dataset so I can look into it? Best, Julius

Hello, I can think of two reasons your analysis is slow: (1) You chose the bootstrap option in the estimation options, that means the analysis runs on 200 data sets, given that the number of samples is specified as 200 in your screenshot; changing …

I know fairly little about PLSSEM, but without the data set there won't be much any of us can do to find the error. It would help a lot if you could create a GitHub issue: https://jaspstats.org/2018/03/29/requestfeaturereportbugjasp/ and uplo…

Hi @hongenggoh, thanks for the suggestion indeed. What you touch upon is quite a controversial topic among researchers. It is of course correct that reliability is no quantification of unidimensionality. The term "Unidimensional Reliability&qu…

Hi Ghislain, thank you for your question. If I understand correctly, this touches on the same subject Leonardo raised, which is to add the component scores or factor scores to the data. Unfortunately, this is not possible so far, but it is on the r…

Nightly builds are a sort of betaversion downloads that might be unstable but mirror the most recent updates to jasp.

Hi Leonardo, sorry for the delay. Seems I do not get notifications from this forum in my email. The option only appears in some nightly builds and is available only in debug mode. However, the option does not have any effect so far, but I have let s…

Here are the issues. It would help out a lot if you could take a look and let me know if anything is missing. https://github.com/jaspstats/jaspissues/issues/1666 https://github.com/jaspstats/jaspissues/issues/1667

Hi Leonardo, I will move your comments to our GitHub issues page. What you mention is 1) a feature request, since you are correct, we do not offer what you seek, and 2) a bug report, because this seems to be a bug :)

Quick update, I have found the issue with the size of the plots. No need for you to explain further. However, it seems as though the size of the plots is something we cannot further reduce. Having implemented the button to avoid saving any samples I…

Dear @GoldenRetriever, I tried to recreate the issue you re describing, and you are right, the jasp files does get way too big. We have managed to alter the code so that the filesize would be reduced quite a bit, however, with 50,000 posterior samp…

Okay. I think this can also be part of the next release. Unfortunately, I dont think I have a better solution for you right now. Cheers, Julius

Hi, this is indeed not a bug, because we prevented an analysis with fewer than 3 variables, because the ifitemdropped statistics would fail in such a case. You are right, mathematically it is possible to compute alpha with only two variable. Unfo…

Dear Sharon, which program or software did you use to compute omega? There is a version of omega (as found in JASP as well) that assumes the scale to be unidimensional. How large is your sample size? And how many levels does your response have? Sev…

Hi, unfortunately within the reliability module there is no way to get a range of inter item correlations. Within the regression module, however, you can get a correlation table for all items. With more than a few items extracting the range might b…
