Hi, I would like to know if there is any recommendation/literature on the performance of the alignment method in the presence of missing data (assuming MCAR/MAR). Can we use multiple imputation alongside this method?
Hello! In a multiple group analysis, the model can be expressed as Y=vg+¦«g¦Ç+¦Å (1)and ¦Ç=ag+¦Æ(2). In your alignment paper published in 2014, the configural model M0 ¡°transforms the factor in each group to mean 0 and variance 1¡± and got ¦Çg0=(¦Çg-ag)/¡Ì¦×g(3).
With equation 1 and 2, ¦Çg-ag should equal ¦Æg. I don¡¯t know how did you get the equation 3 and what does this equation 3 represents. Thanks in advance!
