and found no coherent pattern."
Have you used -codebook- with the -mv- option yet? It sometimes helps with
the detection of patterns in missing values...

Betreff: AW: Re: st: remaining missings after multiple imputation
Hello,
First of all thank you for the advice with the if function in ice. I
will certainly try it as well.
Do these observations contain only missing values on
the variables you use for the imputation?...
...I looked at my variables which have missings despite the imputation
and found no coherent pattern. Do you have any idea?
Best, Anne

It is implicit in the sense that -ice- allows you to specify
an -if- statement. So, you could type something like:
gen byte soft = lnvermgen < .a
ice <varlist> if soft, <other options>
Not all cases of my dataset are considered for the
imputation.
Do these observations contain only missing values on
the variables you use for the imputation?
