摘要:

SummaryThe expected error rates of the sample quadratic discriminant function are studied in the context of two populations with different means and proportional covariance matrices. For the general case of all population parameters unknown the expected error rates are expressed in the form of asymptotic expansions which are evaluated numerically and tabulated for several combinations of the population parameters.

摘要:

SummaryThe author's 1963 procedure for selecting two units per stratum πpswor is generalized to any feasible fixed number of sample units. Simple closed expressions are given for the working probabilities at each draw but the formula for the joint probabilities of inclusion of pairs of units is recursive and tedious to apply. The stability of the variance estimator is believed to be close to the optimum that can be obtained using the Horvitz‐Thompson estimator of total in situations where that estimator itself is optimal. Some suggestions are made for rotation of the samp

摘要:

SummaryThe problem discussed is that of estimating β= (β1, …, βk) in the modelY=βX +ε when X has a specified multivariate distribution and the error ε does not necessarily have a finite second moment, for example, ε symmetric stable. We construct a moment estimator based on the empirical characteristic function and establish asymptotic unbiassedness and normality. Most of the paper is concerned with the case when X is normal. Forms of the suggested estimator are given in (2.5), (4.6) a

摘要:

SummaryThis note gives and discusses balanced row‐and‐column designs for experiments with two non‐interacting sets of treatments, one set not being applied to all the rows. These designs are potentially useful for occasions when trees that have tested one set of experimental treatments are needed for testing a second set before the residual effects of the first have become negligible, but when the experimenter wishes to apply the second set to only some of the rows. The designs are appropriate if the residual and new effects do not int
