Note that in Einstein’s theory h and c are constants, thus the energy of a photon is Each of these is called a bootstrap sample. sample – a sample is a subset of the population. We focus on two important sets of large sample results: (1) Law of large numbers: X n!EXas n!1. g(X, ̄ Y ̄) is usually too complicated. �S���~�1BQ�9���i� ���ś7���^��o=����G��]���xIo�.^�ܽ]���ܟ�`�G��u���rE75�� E��KrW��r�:��+����j`�����m^��m�F��t�ݸ��Ѐ�[W�}�5\$[�I�����E~t{��i��]��w�>:�z Large Sample Theory is a name given to the search for approximations to the behaviour of statistical procedures which are derived by computing limits as the sample size, n, tends to innity. Note: The following Definition 1.1.3The sample space, Ω, of an experiment is the set of all possible outcomes. This means that Z ∼ AN(0,1), when n is large. Chapter 3 is devoted to the theory of weak convergence, ... sure theory. Central Limit Theorem. INTERVAL ESTIMATION: We have at our disposal two pivots, namely, Q = 2T θ ∼ χ2(2n) and Z = Y −θ S/ √ n ∼ AN(0,1).

While many excellent large-sample theory textbooks already exist, the majority (though not all) of them re Most estimators, in practice, satisfy the first condition, because their variances tend to zero as the sample size becomes large.
