Hello Both,
I hope you are doing well. I wish you a happy new year.
I am using 50 imputed data to runmlwin. Due to the size of my database (more than 200000 obs and 85 var), I am using the flong format.
I sorted my data according to level3 level2 level1 but I am getting the following error message ...

Hi,
Thank you for the suggestion and sorry to have bothered you. My problem is sorted, a simple mistake in the command and a bug due to the fact that I' am working with more than 300thousand observations .

Here are the results with the data I provided
*command
insheet using "N:\data.xls",clear ...

I hope that you will be able to use this table.
It is a sample of my data.
Var1 and var2 had missing values and have been imputed
I want to use them in my multilevel model to predict y
using for example
xi: mi est, cmdok: runmlwin y cons var1 i.var2 , level2(area: cons,) level1(id: cons) nopause ...

Hi All,
I have 2 variables :
var1 continuous with missing values (100)
var2 unordered categorical with missing values (25)
I have imputed the missing values
now I am running the following programme:

xi: mi est, cmdok: runmlwin y cons var1t i.var2 , level2(area: cons,) level1(indiv: cons) nopause ...

Thank you for your suggestion
I was trying to find an easiest way. But you are right I should to do it step by step with each imputed variable.

Many thanks to both for your help

Many thanks for your help,

With missing data the programme doesn't run, so I need to impute them before. I am now trying to figure-out how to deal with mi, fp and runwlin.
Maybe I should do it in two steps using mi impute or realcom.
Do you have some advice?

Thanks.

- It works and I guess it doesn't matter if I get this message? :D

Hi ChrisCharlton,

I changed my do file and restarted my computer but I still got the same message with my data and the example I send to you.

end of do-file
