Hi Chunling,
There is some suggestion that imputing on more than 20% of missing data becomes
problematic. The second issue is the nature of the missing data, are they missing
completely at random, at random, or due to some systematic effect. This also has an
impact on missing data imputation.
Thanks Paul

Subject: [amelia] a general question about using Amelia
Dear friends,
Amelia is used to impute missing values, but does the percentage of missing affect the
imputation (I assume so), is there any cutoff point for "good imputation" or
"warning"? I have a cross-country data with 43% of them are missing. Is Amelia a
good choice?
Thanks.
