I like -pbalchk- more informative in this regard, since statistic-based tests (such as t-test) have been criticized for their dependence on sample size. -pbalchk- reports only standardized differences and can explicitly handle categorical variables. I don't however find documentation in the help file if it uses the same formulas for categorical as listed in PC Austin's tutorial: http://www.ncbi.nlm.nih.gov/pubmed?term=19757444 I also found that -pbalchk- can give different results if a large number of variables is tested at the same time vs. if variables are tested separately, I am not sure why.
