--- Comment #3 from Joseph Rushton Wakeling <[email protected]> 2013-06-10 09:06:33 PDT --- Created an attachment (id=1223) Example of error if popFront() is called before first call to front(). This code averages over multiple samples with the following cases: (1) a regular sample of 5 items from 100; (2) a sample initialized to request 5 items from 100 (labelled 0-99); .front is called, followed by .popFront(), and then the remains of the sample is taken. (3) a sample initialized to request 5 items from 100; .popFront() alone is called, and then the remains of the sample is taken. In the last case it is clear that the remains of the sampling process is in practice taking 4 items with equal probability from the items 1-99, when what _should_ be happening is that it is taking 4 items from the items remaining to consider after the first sample point has been taken. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
