Software for a slightly more involved statistical check of PBN files

[nige1]

Published lists of random numbers or hands aren't random. For example, if a table of random numbers comprised ten million consecutive sevens, statisticians would reject it, although such a sequence is as likely as any other. Similarly a hand generator that dealt 13 card suits for half a dozen consecutive deals.

well, these numbers even with stats are not going to help bud out, as these were not generated using "HIS" hands. And there is absolutely no reason to limit the test ot 20,000 deals. He should use 250,000 deals (giving a million unique hands)... or maybe even more. Still, the data presented above easily passes the Chi-Square goodness-of-fit test with unequal expected frequencies, he could even quote the p values (of course, not his deals).... The people at his club will not understand or accept that kind of validation either.

 

 

It would be great to generate a few hundred thousand deals and check out even the void/singleton/7+ card suit statistics.

 

Unfortunately, Dealer4 is limited to 640 deals and BridgeComposer freezes up well shy of 10,000. Any other program out there that could endure a 100,000 deal PBN file to be loaded into it?

As a good Bayesian I don't believe much in hypothesis testing. But is this case the null hypothesis a quite plausible so it makes a lot of sense. A chi-square test on Ben's numbers gives a p-value of 0.639665152.

if you wanted to study hands from BBO

Stephen Picketts bridge browser program would be great

but I dont think there is any new data from BBO or OKBridge since 2007

but the data before that is probably millions of hands

 

it just depends on what type of hand information you are looking for

Again, you can use excel to do this for you. Send me 250,000 pbn hands via email (inquiry at bridgebase dot com) and I will get them into excel with the distributional and hcp information for you (thinks like how many hands have 22 hcp, or 15, as well as the singleton and voids and long suit things.... AND send you back the excel file so you can tweek it to get other information you want.

 

As for bridgebrowser, it is great, but it will never address YOUR hands... unless picket releases it into public domain and allows you to add hands to it.
