I really appreciate your detailed explanation. I have a quick question. Even though I use the same data and enter the same conditions (e.g., class number and step), the information criteria values are substantially changed whenever I try to execute the model. Do you have any solution to that?
Thank you so much for the video. Is the mixture Rasch analysis also possible in Jamovi for test data with raters (e.g., Mixture Rasch in Many-facet Rasch model)? If not, do you know what software should be used?
Are statistical analyzes made by Jamovie accepted in scientific journals? Because I find same differences between SPSS and Jamovie outputs (eg. Omega MC'd = 0.66 (jamovie) / spss = 0.89 )
No, Also Winsteps uses JMLE, which is a biased estimator. Use WINMIRA for Mixed Rasch Model. Or Latent Gold for other mixtures, or Mplus for Mixture Factor Models, or use Conquest for Rasch Models. JMLE-based software should not be used if alternatives are available.
Very simple: Jamvi uses an R package that utilizes a biased estimator for the Mixed Rasch Model: Joint Maximum Likelihood does not provide accurate estimates
It seems there is no more Wright map option under Mixture Rasch model analysis in Jamovi..
Hello good day. I have downloaded the jamovi software but it is not working despite following the procedures involved. What should I do?

You should fix the seed value.

love you sir...sir please make a video on response surface methodology..
Please can I have issues with publication if I use a particular software like jasp or Jamovi ?
I do not think you will have any issues.
Check the list of publication using the software on their websites.
Thank you so much! One question: if I only have one tested population, I should stick to class 1, right?
You should still compare models with different number of classes.

Omega MC'd is estimated in different ways in SPSS and Jamovi. Please watch my videos on SEM in Jamovi.
Is it possible using winstep to run Mixture Rasch?
No, Winsteps does not handle MRM.
@@VahidAryadoust thanks prof

@@MrCycologist thank you
The analysis results of MRM conducted by Winmira is different from the results given by Jamovi, why？
In principle, the technique is the same. But their outputs might be different, due to the use of different estimators.
@@VahidAryadoust Thanks, prof.

JMLE is a 'nono' (biased) estimator. Rasch Mixture models should be estimated with MML or CML.
class is the same as dimensions?
No, they are different.
NO
