Running an analysis on filtered data
Hello I would like to run a linear regression on a subset of my data that I have filtered, in this case only on working age individuals. See attached filter. But now what? When I go to linear regression, I do not see a way of telling Jamovi only to regress on the filtered subset. Am I missing someth...

Shapiro-Wilk normality test comes up empty
Hello, I'm using Jamovi 1.6.18.0 on a Mac (OSX 11.2.3). I would like my students to be able to run a normality test after a regression. The regression runs fine. But for some reason in Jamovi I get 'Nan' for the statistic. See attached. Screenshot 2021-03-26 at 14.13.58.png Any thoughts about what m...

Re: heteroskedasticity-consistent (HC) standard errors
Thanks Jonathon - that does help tidy things up - much appreciated. This solves the first issue. But I still need all the many lines of preamble code from @MAgojam to get robust SEs. I suppose I can get my students to copy and paste the syntax. Maybe a wish-list item for a future iteration - in Stat...

Re: heteroskedasticity-consistent (HC) standard errors
Ok...thanks for all your help. I have made progress, and now get output with robust SEs, but I still have a few questions. @jonathon I put my_model on its own line at the end. But as you can see from my code below, there is a LOT of syntax to run here. And also the commands build on a Stata dataset....

Re: heteroskedasticity-consistent (HC) standard errors
Again, many thanks Maurizio - I really appreciate your help. I copied and pasted your code (adjusting the path slightly - I'm on a Mac not a pc), but no matter how I adjust, or which version of your code I use, literally nothing happens. I get no output, and no error. For instance- running the follo...

Re: heteroskedasticity-consistent (HC) standard errors
Thanks so much. The code is failing on something very simple - I'm not sure how to refer to the data - forgive me, I'm a Stata person, not an R person. If I want to run the code on an open Jamovi dataset (.omv), how do I do that? I tried something like my_data <- lab_data_baseline.dta ('/Users/tk1/D...

Re: heteroskedasticity-consistent (HC) standard errors
Hi @Magojam et al, It is very odd that robust SEs are not a feature, seeing as they are so commonly used. I tried your code, but it seems to just output the same set of non-robust standard errors. See attached. Screenshot 2021-02-17 at 11.47.43.png Screenshot 2021-02-17 at 11.48.01.png Any thoughts?...

Added variable/partial regression plot?
Hello,
I'm wondering if there is a way to generate a partial regression plot (or added variable plot) in Jamovi. I would want to use this to look for influential observations in a linear regression - in Stata this is avplot, or (I think) partial_plot in R.
Any thoughts?
Thanks
Tom
