Player and Skill Costs: least-squares analysis
Posted: Mon Dec 08, 2014 7:29 am
I recently ran a mostly unrestricted least-squares analysis of all players from the official races against their rookie skill values (just because I was curious if it could be done and if it would have any intuitive appeal), and came up with a very interesting set of results for *implied* skill, stat, access, and misc costs (and therefore player costs). There are limitations simply because in many cases the number of data points is low (eg. Strong Arm appears only on the Treeman so tends to act like a plug figure for std error; there are many such examples). However the nice thing is that, despite its imperfections, it still yielded the following players as "most mispriced", which seems more or less appropriate:
1. Dwarf Runner (overcosted by 9)
2. Blitz-Ra (over by 9)
3. Marauder (under by 7, even with M access valued at 0)
4. Orc Thrower (over by 5)
5. Human & Skaven Throwers (under by 5)
7. Wood Elf Thrower (over by 5)
8. Norse Lineman (under by 5)
9. Orc Lineman (over by 5)
10. Underworld Skaven Thrower (under by 4)
This isn't meant to be critical of Galak's sytem -- obviously there are reasons why a MA6 player should be more valuable on a slow team than on a fast one, for example.
Note that the model also generated odd results, such as this: characteristics (positive or negative) worth 0 value included Passing Access, Mutation Access, Mutation on Doubles, any ST greater than 5 (ie ST6 and ST7 are worth the same as ST5), General on Doubles (neg), and No Access to Apo (neg). Also Leap was valued at 0 -- explained by the fact that Blodge Premium (12) and Very Long Legs (13) tended to distort Leap's value as when it appears it appears only with those skills. I'll have to manually tweak the restrictions to correct for this and see what happens.
Also, interestingly, positive skills yielded an average value of 11, suggesting perhaps skills are valued too highly across the board. How would it change the game, I wonder, if all regular skills cost 10k instead of 20k?
