I think I did not explain it well
. So I want a stat that is not a stat for a specific opponent, but for the player population I play against, since many times I do not have enough hands to get accurate stats for one player. Lets say I played 9 hands against an opponent so far and I am facing his first 3bet. This would give 20% percent 3bet, but obviously this is not an accurate number because of the small sample. In this case I would use the population tendencies for my decisions as the best approximation I have. Probably the regular way would be to create an alias which includes all the players, however I would try to find an easier way for it. Since I always play HU, all stats on opponents I have are from the hands they played against me. So I thought instead of creating a stat for them, I would create a stat for me. Whenever they 3bet, I am facing a 3bet, so my 3bet-facing stat should be actually their average 3bet. I never raise preflop more than 3x (only if I raise allin), and obviously never below 2x, this is why I thought this should be OK (they cant 3bet if I openshove preflop, thats why I need to filter somehow). Is that correct this way - do I get the actual 3bet % of the population? Is there any other way to get a population stat easier?
The ideal would be if I could weight the stat for specific player with population tendencies (Bayes theorem), but for that I would need the standard deviation (SD) for a given stat. Can I somehow get a specific stat out of the database for all the players? In a format where I would get for example all the 3bet stats for everyone (exept for me) together with the SD (or without it, separate stats for everyone in some exportable format - so I could calculate SD). Without having to check it for everyone one by one, obviously.
