Dear all
When set
mxMatrix(type="Full", nrow=1, ncol=2, free=TRUE, values=c(0,0), label= "mean", name="expMean")
in twin ACE model, i found if i set label="mean", the
twinACEFit@output$estimate return 4 values with label (mean, a,c,e)
if the label item not set
mxMatrix(type="Full", nrow=1, ncol=2, free=TRUE, values=c(0,0), name="expMean")
twinACEFit@output$estimate return 5 values with label (NA,NA, a,c,e) and the first two mean values are not exactly the same.
Which one is correct?
