Hi Martin, I helped to develop Amelia, so I can try to take a shot. In a non-mathematical way, Amelia works by filling in missing values with imputed values that are consistent with the observed relationships in the data, plus some random noise. Thus, Amelia creates multiple imputed datasets that

Dear all. First of all, my english isn't verry good, but I hope I can convey my concern. I've a general question about the Amelia algorithm. I'm no mathematician or statistician, but I had to use R and impute and analyse some data, and Amelia showed results that fitted my expectations. I'll have t
