A set of jointly sufficient statistic is defined to be minimal sufficient if and only if_______________?
Correct answer: B. It is a function of every other set of sufficient
- A. It is a function of some other set of sufficient statistics.
- B. It is a function of every other set of sufficient
- C. It is a function of any sufficient statistics in the set.
- D. It is not a function of every other set of sufficient statistics.
Explanation
A minimal sufficient statistic contains the least information needed for sufficiency and can be expressed as a function of every other sufficient statistic. Option a reverses this relationship and would not characterize minimal sufficiency.
