The next concept is that of a complete statistic. As we have seen, the, identity function is a sufficient statistic so this choice does not simplify or summarize, anything. In data reduction, there are two key principles that play a role in ensuring the statistics being used are efficient in reducing the data and contain information that isn't misleading: those of sufficiency and completeness. 0000015550 00000 n /BBox [0 0 5669.291 8] /Matrix [1 0 0 1 0 0] >> Sufficient Statistics Let \(U = u(\bs{X})\) be a statistic taking values in a set \(R\). stream Contents 1 Definition 1.1 Example 1: Bernoulli model 2 Relation to sufficient statistics 3 Importance of completeness 3.1 Lehmann-Scheff theorem endobj The Indian Statistical Institute (ISI), is a unique P.
