Hi OpenMX community!
I have a probably strait forward question. I'm running simple Univariate ACE models with covariates. My dependent variable has non-normal distribution. Should I normalize my data, for example using the R function scale? Should I normalize my covariates also? My estimates only change slightly, my Chi-square values are basically the same, but my CFI and TLI values change a little bit, should this be of concern?
Thanks for your help!
