completeness
Def.
Let f(s│θ) be a family of pdfs or pmfs for statistic S = S(X_1,...X_n).
The family of probability distribution is called complete if
E[u(S)]=0 for all θ implies u(S)=0 with probability 1 for all θ.
Equivalently S is called a complete statistics.
上色的那句話 我看不懂是指什麼意思
可以請各位告訴我一下是什麼意思嗎？ 謝謝
