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

in SEM. Possiible predict output using SEM coefficients? Comment by julius March 28

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 non-linear data? Question 3) Yes, can't handle missing data, that is, cases with missings are deleted befor…

in Fully upset with Partial least squares SEM Comment by julius March 27

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…

in JASP Omega different from RStudio Comment by julius March 19

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

in JASP Omega different from RStudio Comment by julius March 18

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

in Exploratory factor analysis Comment by julius February 14

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/jasp-stats/jasp-issues/issues/new/choose. It would…

in Errror in Valid Object Comment by julius February 13

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

in Assessing measurement model when using PLS-SEM Comment by julius November 2023

Hi gvt, what do you mean by "non-parametric" 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…

in Reliability: Multiple categories at once? Comment by julius October 2023

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(1-rel). I dont know about the confidence interval though. Julius

in Standard Error of de Measurement Comment by julius October 2023

Hi, there is an open pull-request for the HTMT and AVE for the SEM module https://github.com/jasp-stats/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…

in Correlation matrix when using SEM Comment by julius August 2023

And given that there was this bug https://github.com/jasp-stats/jasp-issues/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.
