Hi, someone pls help me. I am trying to run a mediation and moderation but am

Have you run descriptives on each variable in the analysis? And is the N for each variable the same and does that number match the number of cases in the analysis file?

Here are two tricky instances that I remember, for "unexpected missing" cases.
2) Having mis-written a Select If or Match Files in code that is only used for the run-gone-wrong.
(Do your checking right after the code that produced N=7 valid cases.)

Hi Sara,
I’ve used the Hayes macro only a very few times so I’m not very familiar with it. But, looking through the output (Thank You!) I see that model summaries for
observe and ptsdonly show dfs of 75 and 74, which seem right given an N of 77. I take that to mean that you had no missing data for the regression models.
You can replicate parts of the macro output using just the regression command. You need three unstandardized coefficients: neuroonl predicts observe (XM); observe
predicts ptsdonly (MY); and neuroonl (XY), observe (MY2) predicts ptsdonly. First of all, you should get the same model and model summary numbers as in the output. You can also compute the indirect effect as XM*MY. The direct effect is XY. I bet your numbers
will match Hayes. However, I understand none of that explains the message. I think Hayes has a website. Look there.
Gene From: Sara Stanley [mailto:[hidden email]]
Hi Gene, yes I re-ran the descriptives and N matches. Kind regards Sara Stanley From: Maguin, Eugene <[hidden email]> Have you run descriptives on each variable in the analysis? And is the N for each variable the same and does that number match the number of cases in the analysis file? |
Thank you Gene, I realised that it was that PROCESS cannot handle copy and paste data. I went back to an earlier version and ran that with success. If you come across this sort of problem again with anyone ask if they have done the same.
