Dear Developer or helpers
As a beginner in Rasch analysis, I'm interested in analyzing a questionnaire using Jamovi. The questionnaire is traditionally analyzed using the Andrich rating scale model. Can I perform this type of analysis within Jamovi?
I appreciate your kindness

Hi
You can analyze them by using snowRMM or snowIRT module.

Dear Seol,
Thank you for your answer. As a beginner in this field, I've noticed that Winsteps is commonly used to validate Likert scale questionnaires. I would appreciate it if you could answer a few more of my questions
1. Does the SnowIRT program convert scales into logit units (function logarithm)?"
2. Can SnowIRT calculate item reliability, person separation index, item separation index, and the target (mean difference between people and items) for the entire questionnaire?"
3. Can differential item functioning be analyzed using SnowIRT?"
4. Can this program plot the Andrich threshold, a graph showing the relationship between category probabilities and the measure relative to item difficulty?"
I think that these questions are beneficial for all beginners who would like to validate the questionnaire.
I will look forward to your answers.
I would like to express my sincere gratitude for your assistance.

Dear AUN22
I think you should use the snowRMM module rather than the snowIRT module. I want you to take a look at the example files and analysis options in the snowRMM module first.
