Various tables and plots
. tab DSO quintileDSO
. scatter quintileDSO DSO
. quantile DSO, ms(none) mla(quintileDSO) mlabpos(0)
should help you see what you are doing.
The command -xtile- should be documented thus:
"This command can help you throw away quantitative information when for some perverse reason that is what you want to do."
