How is st dev bb calculated in HM2? In HM1 it was in the range of 70 and per 100 hands, now it is around 10, even after a short session of only 60 hands with a 100bb win. Looks like something is wrong. Anyhow, please explain how this is calculated.
To convert, you just multiply or divide by 10 (square root of 100)
but if i try to run a simulation like on evplus or calculate confidence intervals myself, which value to use? the winrate is /100 also, so i should use hm1 value? (although it doesnt say bb/100 in the stat there)
also: is the standard deviation of the sample or of the population calculated?
i have 2 hands in my database. one i lost 17.2bb and one i split the pot and won/lost 0. mean is -8.6bb
HM1 says for standard deviation: 120.21
how is that value calculated? i just dont find any formula that fits
sorry for coming back to your reply a bit later...
thanks for the detailed answer. i read the link, yet i dont really understand what the difference between stddevpa and stddev numerically or lets say in this example. to me it seems stdevpa and stddev only differ in such a way:
if in one cell there is a text string, std dev doesnt treat it at all and stdevpa treats it as a value 0.
this shouldnt make/explain any difference in the example of mine mentioned above or should it?
can you explain the exact calculation/difference in the simple example of mine?
also for evplus i should use the hm2 value then rather than the hm1 value?
