Re: Split and Apply
I know this method, but I would like to see the combined data in one place. lme4 or nlme got a neat function lmList which achieves exactly this. In future, I would like jamovi should have this capacity to split the data and apply t-test, anova, lm etc and get combined results. I have seen this capab...

Split and Apply
Hi, I would like to split my mycars dataset into three subsets based on the cyl variable and apply linear regression on each of these datasets. Is there any way I can do this? Similar R code to achieve this is: models1 = lapply(split(mtcars, mtcars$cyl), \(x)lm(mpg ~ disp, data = x)) tidy_list = lap...

Re: Creating lag and differen variables
Yes. I got the desired results. But please include these functions lag, lead, diff too in future versions. Followup question, is there any possibility that any one create a time series module based on fpp2 or fpp3?

Re: Creating lag and differen variables
Yes. This is what I need. But Lag, Lead, diff are more used verbs in econometrics.
Lag -> OFFSET(A, 1)
Lead -> OFFSET(A, -1)
diff_1 -> A - OFFSET(A, 1)
diff_2 -> A - OFFSET(A, 2)
Lag -> OFFSET(A, 1)
Lead -> OFFSET(A, -1)
diff_1 -> A - OFFSET(A, 1)
diff_2 -> A - OFFSET(A, 2)

Creating lag and differen variables
Hi,
Is there any function to create lag and first, second, ... difference variables in Jamovi?
Thanks.

creating grouped mean variable
Hi,
I would like to have a functionality similar to ave in base R to create a grouped mean variable. I have a dataset with a continuous variable x and group. Now I want to create a new variable where all observations in a particular group have the same mean. How to do?

LRT test df difference
Hi, While comparing Config, Metric, Scalar models for MI, I am getting different results while doing manual calculation with constraints score test. Is it comparable with LRT test? Is there any way that jamovi provides a table to compare config vs metric, scalar vs metric using lavTestLRT function o...

For the second question, PIF_3 ~ c(a, b)*1 is working.

Re: Releasing constraints in gamlj
Quick followup,
How to release PIF_3 intercept while doing scalar invariance? Seems the group.partial is not effective here.

Releasing constraints in gamlj
Hi, I have a 4 item multi group model as described here. Exercise 3A. https://stats.oarc.ucla.edu/r/seminars/lgm/#s2 Now I would like to release the first item and fix the second item loadings to (1, 1). This is possible in lavaan by setting auto.fix.first = FALSE which is missing in gamlj. Is there...
