Confidence interval for EV BB/100

Postby erdnase17 » Tue Jun 18, 2013 12:35 pm

I would like to make a custom stat that shows the 95% confidence interval for the All-In Adj Equity BB/100.
This post http://www.quantitativepoker.com/2011/0 ... n-and.html suggests a very nice method based on the All-In Adjusted Standard Deviation BB/100 which I defined already.

The interval can be calculated as [lower, upper]
where lower|upper = EV Adj BB/100 +- 1.96*(Adj Std Dev BB/100)/sqrt(cnt_hands/100)

Unfortunately it seems like I have to define the lower and upper values as separate statistics. Is it possible to represent this interval as a single statistic with an appropriate format function?

Thanks.

You should be able to define the values as individual variables, and then combine them in one statistic using a fancy format expression. The details on how to build these kinds of format expressions can be found in this post - it was written for PT3 but works equally for PT4.

Thanks, that helped. I will try to submit the stat to the warehouse so you guys can review it.

Now I noticed I meant to post this in the PT4 forum but posted here by mistake. Is it possible to move the thread?
Thanks.
