Hi Belzile

Good news.

All graphs are produced simultaneously when you select the analysis option in dichotomous and polytomous model.

The updated version will be available on Monday. I will let you know. Thanks for your request again.

Hi Implementing the feature to display a separate graph for each item requires a fundamental change to the module's structure. The output for plot must be converted from a single plot object into a dynamic array of plots. This change affects more than just the plotting function itself: Initializatio...

Hi

@jonathon. Waiting for an update to jamovi 2.7 sooner or later. When it is updated, please reinstall the snowCluster module from the jamovi library at that time.

Example: >column1 <- c(10, 20, 30, 40, 50, NA) > column2 <- c(8, 17, 28, 39, NA, 60) > # Incorrect calculation > m1 <- mean(column1, na.rm=TRUE) > m2 <- mean(column2, na.rm=TRUE) > pooledSD <- sd(column1 - column2, na.rm=TRUE) > d_wrong <- (m1 - m2) / pooledSD > d_wrong [1] -0.4898979 > # Correct ca...

Here is the correct way to calculate Cohen’s d for a paired samples t-test in R diffs <- column1 - column2 d <- mean(diffs, na.rm=TRUE) / sd(diffs, na.rm=TRUE) If there are missing values (NAs) in different places in each column, then length(column1) and length(column1 - column2) may not be equal. A...

difference <- column1 - column2 # sd of difference sd_diff <- sd(difference, na.rm = TRUE) # standard error of difference sediff <- sd_diff / sqrt(length(na.omit(difference))) # Cohen's d m1 <- mean(column1, na.rm = TRUE) m2 <- mean(column2, na.rm = TRUE) d <- (m1 - m2) / sd_diff In short, For paire...

Hi

You can use jYS module in jamovi library now.

Hi
Thanks for using MFRM model in snowIRT module.
I'm not helping with statistical interpretation, but here's the MFRM model reference I used to develop the module. I hope you find this helpful.

Hi

Thank you for your suggestions. jamovi is an open source statistics program and we are waiting for another module developer to implement the method you suggested.

Kind Regards
