The format of the matrix displayed in stata (matrix list e(V)) is massive when running the model with a lot of covariables.
Is it possible to collect them in a different ways (like the column way you are suggesting)?

Thanks

Great thanks you for your suggestion.
I would like to display c1099 (covariance matrix of fixed parameter estimates) back in stata (for future use if needed) .
It is possible?
If yes, can you please help me?

Many thanks

Hi ChrisCharlton,

Changing column c1096 value to 0.0001 if 0 resolve my problem when I am running a model on imputed data (the Rubin rules is no longer crashing).
But it has created another issue when I am using the model on complete cases. I am getting the following message:

Brilliant ! It works.

Many many thanks

I am running the model on a sudgoup of an imputed variable. So I have different sample size by imputation number.
In some of them like imputation4 I have few observation at level3.
So all the programme abort at imputation 4 because level3 variance is 0 and the Rubin rule couldn't continue ...

Hi ChrisCharlton,

Many thanks for your help.
Unfortunately, I couldn’t get it to work. The programme aborts because the variance is still going to 0. (I assume it is considering 0.0001 as a starting value so, the problem is not my starting value)

I noticed that when I change the variance manually ...

Many thanks ChrisCharlton for your response.
I have changed the initial value but the variance couldn't change (still going to 0).
I will try to change the runmlwin.do file directly, but I am not sure that I Know how to change the section you showed in order to make the following changes:

Hello,

I am using Runmlwin and mi estimate.
My sample vary by imputation number and I am getting a variance=0 for some of them and it prevent Runmlwin to continue (with esampvaryok).
Without the nopause option, I have tried to remplace variance= 0.0001 in MLwiN when it is estimate to 0 using ...

I am having trouble with mi estimate and runmlwin. I have a set of 30 imputed data.
This is my programme;
