I'm a little confused. Please can you post the output from str(dati), summary(dati) and summary(fit) into the question.

| Jan 4, 2020 at 15:18 | comment | added | Filippo Gambarota | I have a SD of 0.9 for the control group and 1.35 for the other group (collapsing all other factors) | |
| Jan 4, 2020 at 15:16 | comment | added | Robert Long | You said the variances are different in the 2 groups so I asked you what they are. I mean the value of those variances. | |

| Jan 4, 2020 at 12:21 | comment | added | Robert Long | What are the observed variances ? | |
