In the vain of more data is better... these are all of my guys who are at 8 or 9 Game Shape.

(913991)
Gameshape 9
Stamina 8
Salary $ 36 390
DMI: 413600

I list him cause his stamina dropped from 9-8 last tu, dmi dropped by 1000. He didn't play on training position last week.

Perhaps this helps.

Please post the following (only!): game shape, visible salary, DMI, stamina, optional: player id as link
Imaginary example (I don't have any real ones on my team):
GS, Salary, DMI, Stamina, playerId

If the real relationship is DMI= (GS coeff)* SALARY + (some vector of other skill factors) simply looking at stamina might be insufficient. It is quite possible that skills enter the DMI calculation both as logs (in the salary formula) and as linear values, separately.

Possible, but I doubt that free throws impact DMI. The only other contender then seems to be experience, and I'm afraid we'll get too little diverse experience data to check this anyway, since only the small sample of observations that have a game shape with very low sublevel yield useful information for this research. But stamina does seem to play a role. Of course the DMI formula could be arbitrarily complex to tease us, but let's get there when a simpler approach has failed ;-)

I am not talking about free throws only -- any player skills can enter the DMI calculation as a linear combination. Again, I provided a simple example: if DMI contains the the salary (as predicted by your calculator, and based on current skills), which is a linear combination of skills, there is nothing stopping the "extra factor" from being a sum of any (or all) of the player skills times an appropriate coefficient.

Therefore, if you omit any skills just because they enter salary already, you might be biasing the results.

yes I understood you. but then the observation about DMI at proficient game shape would look odd. everything's possible though, especially with a deliberately meaningless index, but I'd like to stick with the simple approach for now. anyway what we need right now is not so much more theory but more data :-)

I think we have agreed that there is ample evidence that in proficient GS,

DMI = 10*SALARY + something,

and that you're looking for the something. How will it look odd if something = B*(sum of all/some player skills), where B is a coefficient?

I understand you need data, I just want to make sure you're collecting the right one.
