I've spent some time looking into the effects of traits as they pertain to stat and skill totals. I got these results by creating a girl with 50 in all stats and skills. I then loaded her into the game and recorded her base and derived stats. I then modified the girl, giving her one trait and recorded the changes, making adjustments to her base stats when the effect of a trait brought a stat to the minimum or maximum.
Question: Wouldn't it have been easier/less tedious to simply look at the game code?
Answer: Most likely yes. But looking at the game code tells me what a trait is intended to do. Loading the trait up in game and recording the changes tells me what it is actually doing. I feel that the difference presented by this nuance is enough for me to take the approach I did.
I've attached an .ods file with my results, which detail the individual changes every trait makes to a girl's core and, by extension, derived stats. .ods is the default extension for Open Office, which is the program I used to create the spreadsheet. I've also attached the same data in .xml format in case someone wants to view the data without Open Office. I can likely provide the data in other formats as well, just ask.
What I have not yet researched are the secondary effects some traits add to girls. I know these effects are can rage from unnoticeable (aggressive does more damage in combat) to unbalancing (incorporeal girls don't get tired). If anyone who has played the game a lot can come up with a list of traits with secondary effects that significantly affect gameplay, for good or bad, I would be very thankful. A partial list off the top of someone's head would be useful as well.
One last thing to note are fetish categories. Some traits make a girl qualify for a fetish by themselves; these have been noted in my data. However, fetishes got more complex when I realized that combinations of traits grant fetishes that the traits individually do not. With 73 traits unique complete understanding of how fetishes are assigned basically requires reading code.
Now to make this post a little more interesting here are top and bottom 5 traits that change a girl's core stats:

Masochist adds a commanding 150 to a girl's stat totals. In very beneficial places too: +50 to BDSM Constitution and Obedience.
