jamovi

Hello. I was hoping someone could help me with the most appropriate test to use in Jamovi for the following analysis. I have two continuous variables that I am comparing in a small data set (n = 18) of non-normally distributed data so I have used a Spearman's correlation. I now want to adjust the data for potential confounders (age and BMI). For normally distributed data I would use a linear regression. Is there an option for performing a non-parametric multivariate analysis in jamovi? Thanks very much

There are a few options, although your sample seems really thin.
You would need to use R (unless I am wrong and a library has already been developed for Jamovi).
Perhaps the Siegel Transformation would be your best option.
Have a look at Mangiafico's magnificent handbook:
