Hey CSTan and patc3, I've received your question(s), but answering will require some further consultation with some colleagues. I'll get back to you asap. Best, Michael

Hi Carolin, If you use a SEM model to regress latent variables (factor that you modeled yourself) on one another, you don't actually need to assess their reliability in my opinion. Composite reliability estimates such as cronbach's alpha are used …

Hey drpablorogers, You are using the Santorra Bentler Test here. The basic principle of this test is that it corrects the LR test for certain robust estimation methods (see https://www.statmodel.com/chidiff.shtml). The underlying R-command is lavaa…

Hey Georgios, The loadings are unstandardized. You can get the standardized ones by choosing a standardization (usually you would go for "All") in the Advanced option. So let's first disentangle what modification indices are. Modification…

It wouldn't work out in practice to manipulate the columns without the knowledge of the user. The quantitative interpretations of model parameters depend on the scaling of the variables, so the users must be aware of this. If you don't want to thin…

Hi Michael_Jasper, Indeed, lavaan is the underlying (R) package, and these errors are given by lavaan. So, in general, this is not a problem specific to JASP, and perhaps the lavaan community (https://groups.google.com/g/lavaan) might be of better …

Hi Michael_Jasper, Could you please attach a screenshot of the error message you get? Best, Michael

Hi Michael_Jasper, This is a good question, and I understand your confusion here. The reason why the results can contradict in this case, is because the p-value comes from a different test, and not form the (bias-corrected percentile) bootstrap. Th…

Hey Michael_Jasper, It is correct that "Percentile" in JASP corresponds to the percentile bootstrap. However, the "Bias-corrected percentile" in JASP refers to the adjusted bootstrap percentile (BCa) method that only corrects fo…

Hi Michael, This is still an option. The plot is made using the plot tab in the Descriptives module. It's a scatter plot with histograms of the two variables on their respective axis. You can see how this plot is specified in detail in the screensho…

Hi Anabela, As of now, it is indeed not possible to run a second-order factor model with more than one second order factor using the CFA module. I'm glad to see that you found a solution. I would have suggested using the SEM module for this too. I…

This is indeed a good question, and this will be a relatively long answer accordingly. In order to test for measurement invariance, you need to fit a sequence of models. First, in the configural model all parameters (i.e. factor loadings, intercept…

@Rashmin, can you please email me a .jasp file of your data and analysis to j.m.b.koch@protonmail.com? You can get that file by running your analysis, clicking Save As -> Computer in the main menu, and then saving in the desired folder. Best re…
