Re: Buy in requirements
Donkeykong , it is true .
Your variance is NOT equal if you have the same win rate . You're assuming that the probability you win each individual game is the same when it's not . If this were the case , that is , the probability you win each individual game is always y% , then two players with the same win rate have the same s.d . Two players can have different styles and still end up with the same win rate over time , or close enough . Every players s.d is different and it's not a function of your win rate . They are two completely different things .
The variance of a binomial distribution is n*P*(1-p)
s.d = sqrt[n*P*(1-p)] but this assumes p is constant for each game .
