Re: Unordered imputed variable

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 Man...

Re: How to run a multilevel model using fractional polynomia

Thank you for your suggestion :D
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

Cheers

Re: How to run a multilevel model using fractional polynomia

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.

Re: How to run a multilevel model using fractional polynomia

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. :oops:

e(sample) changed across estimation runs
r(498);

end of do-file

r(498);
