Hi I have a dataset from biological data with forty samples whichh relate to four different treatments. Each sample has thousands of values but as usuual contains
missing values I want to use EM to imput these missing values. I am doing tthis using amelia. Do I need to specify the various groups or can I just use the amelia command on the whole dataset (zz) together. zzAmelia <- amelia(zz[,-1], m=5) Also im not sure which value of m should be used Thanks in advance ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
