Weighted standard deviation r
The “P factor” established in your f$P function is in fact a kludge to compensate for the fact that opponents who fold have weaker hands. You may need to change your f$P function if using weighted prwin. If your opponents at flop include a big blind who has not been raised, no weighting will be applied to his hand, since no assumptions can be made about it. It will also be turned off if your f$P function specifies more than 13 opponents. If f$willplay is absent, or returns a zero value, the prwin weighting is turned off. For DLL developers, there is also the option to use ) which is based on published data about hands players actually take to flop, and varies from conventional ones giving win probabilities, particularly in the way it favors suited hands! In the absence of statistical support it is not recommended that you implement f$topclip or f$mustplay unless you have a good picture of the standard of play at a table. OpenHoldem’s “Weighted prwin” is based on a fairly simple model using pre-flop behavior. Essentially it aims to put your opponents on cards as accurately as possible.

Factors which can be used to make inferences about cards include willingness to pay to see flop, betting behavior when faced by common cards, and historical information about opponent behavior. The prwin values you obtain will be within 1 standard deviation 67% of the time, within 2 standard deviations 95% of the time, and within 3 standard deviations 99% of the time.Ī weighted prwin is one which is calculated by making informed selections of the cards that opponents are likely to hold, and using these cards in the calculation of your win probability. In our case, it would be 100,000 required iterations. = 0.001).įind that standard deviation in the top chart and read off the number of iterations required.

To get 1 standard deviation, divide by 3 (to give std. For example, if you are happy with getting prwin's of 0.846 - 0.852 99% of the time for AA headsup preflop, your error would be (0.849) +- 0.003.
