wOBA & FIP Constants

Are the constants from year to year available in-game? Looking for something similar to these -> http://www.fangraphs.com/guts.aspx?type=cn

For Fangraphesque stats for Batters do this:

Pick a Batter < Go to "Batting Stats" < Under the "Career Batting Stats" tab < Click the Tab that says View < Click "Extended Batting Stats"

Should look like this:

For Fangraphesque stats for Pitchers do this:

Pick a Pitcher < Go to "Pitching Stats" < Under the "Career Pitching Stats" tab < Click on the Tab that says View < Click "Extended Pitching Stats 2

Should look like this:

Extended Pitching Stats has W%, QS% and SV% and other Reliever oriented statistics

I think we can all agree that Andrew Romine and Tony Wolters deserve 5 star ratings right?

I'm guessing you're looking for the coefficients, not the constants. I don't think the wOBA formula changes from year to year in OOTP like it does IRL. So far as I can tell, the formula for wOBA in OOTP is:

wOBA = (.625*BB + .677*HP + .842*1B + 1.222*2B + 1.408*3B + 1.965*HR) / (AB + BB - IBB + SF + HP)

I arrived at that formula using some data from my online league. I transformed wOBA using the denominator in the formula on the website you provided:

wOBA_t = wOBA * (AB + BB - IBB + SF + HP)

I then used linear regression to predict wOBA_t using BB, HP, 1B, 2B, 3B, and HR with the intercept fixed at zero. The R^2 for the model was .9997, so nearly a perfect fit.

Every league and OOTP universe is going to have different constants for FIP and wOBA. I've not been able to find them in game, and I suspect that they are not available to us.

I also don't know whether the game generates them as it goes or if it uses a static formula as ASURay notes above.

I've rolled my own (read about it in the first link in my signature if interested). Rolling my own, I'm averaging ~.012 variance on wOBA. Not great.

I've got similar accuracy on FIP (~0.11) but am within 2 points on FIP-.

All this to say, if you're looking for wOBA scale and the coefficients in game, you're not going to find them. Likewise the FIP constant. If you roll your own, you can get close.
