[edit] Insight

Could someone write a few words on what the significance of the score is?--Adoniscik (talk) 03:21, 10 January 2008 (UTC)

[edit] Statistic?

There is an apparent contradiction between the present article and cited article "Sufficiency (statistics)". The present article says, "Note that V is a function of θ and the observation X. The score V is a sufficient statistic for θ." However, "Sufficiency (statistics)" states, "A quantity T(X) that depends on the (observable) random variable X but not on the (unobservable) parameter θ is called a statistic." This implies that V (being a function of both X and θ) is not a statistic. Thus, it also follows that V cannot be a sufficient statistic for θ. Is there a resolution to this apparent contradiction?

You're right. It's really not clearly explained here. I'll be back soon... Michael Hardy 22:22, 4 August 2006 (UTC)

I agree, you're right. Having calculated a few scores recently, the score is clearly not necessarily a statistic, and so cannot be a sufficient statistic. The sentence ought to be removed (or at least replaced with one saying that if it is a statistic, then it is sufficient if anyone can prove that). —Preceding unsigned comment added by 89.240.198.146 (talk) 17:43, 23 May 2007 (UTC)

You guys are right. I have removed this clearly erroneous statement. --Zvika 08:12, 24 May 2007 (UTC)
