can someone enlighten me how to use the sqrt command ?
Taken from the description:
Code: Select all
-sprt elo0=E0 elo1=E1 alpha=α beta=β Use a Sequential Probability Ratio Test as a termination criterion for the match. This option should only be used in matches between two players to test if engine P1 is stronger than engine P2. Hypothesis H1 is that P1 is stronger than P2 by at least E0 ELO points, and H0 (the null hypothesis) is that P1 is not stronger than P2 by at least E1 ELO points. The maximum probabilities for type I and type II errors outside the interval [ E0, E1 ] are α and β. The match is stopped if either H0 or H1 is accepted or if the maximum number of games set by -rounds and / or -games is reached.
H1: Elo_P1 > Elo_P2 + 10 ( at least 10 elo better )
H0: Elo_P1 < Elo_P2 + 25 ( not more than 25 elo ?! )
-sprt elo0=10 elo1=25 alpha=? beta=?
So, what values and what format must be used for alpha and beta ?
Do i even understand the usage of H0 ?
Thank you in advance.
