Talk:Score (statistics)

From Wikipedia, the free encyclopedia

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)
