Hello Gavin,decile percents: 69.9% 21.0% 6.3% 1.9% 0.6% 0.2% 0.1% 0.0% 0.0% 0.0% probability of fist/last percent of the range: 11.3% 0.0%I would suggest that probabilities should NEVER be expressed inpercentages! As a percentage probability looks weird, and is neverused for serious statistical work - in my experience at least.I think probabilities should be expressed in the range 0 ... 1 - i.e.0.35 rather than 35%.I could agree about the mathematics, but ISTM that "11.5%" is morereadable and intuitive than "0.115".I could change "probability" and replace it with "frequency" or maybe"occurence", what would you think about that?

`You may well be hitting a situation, where you meet opposition whatever`

`you do! :-)`

`"frequency" implies a positive integer (though "relative frequency"`

`might be okay) - and if you use "occurrence", someone else is bound to`

`complain...`

`Though, I'd opt for "relative frequency", if you can't use values in the`

`range 0 ... 1 for probabilities, if %'s are used - so long as it does`

`not generate a flame war.`

I suspect it may not be worth the grief to change. Cheers, Gavin -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
