Here we go -- look at the character pages (Encylopedia -> Places & People -> Characters -> Chrono Cross). Thankfully ZeaLitY has collected the beginning stats (star level 0) and ending stats (star level 99) for each character.
Sometime we'll need to run a search for these values in hexadecimal using a hex editor and see whether there's a stat table that defines each character's stats. I imagine some algorithm is involved as well, and maybe the stat progression algorithm can somehow produce all the values on its own, without the need for a stat table. In which case, Chrono Cross stat editing will be more difficult than what I had bargained for.
