摘要:

AbstractDirect kernels, due to LAUDER(1983), as an alternative to the indirect kernel method in discriminant analysis are considered. It is shown that direct kernels may be based on any kernel function known in discrete density estimation. The choice of smoothing parameters is based on general loss functions and a family of loss functions which are specific for the discrimination problem is introduced. Examples with distance dependent and distance independent smoothing parameters are given to illustrate the applicability.

摘要:

AbstractIn this paper properties of an estimator of the population mean on current occasion under successive sampling scheme, when various weights (φh'S) and regression coefficients (βh,h‐1) are estimated forh≥ 2, have been studied. Some empirical results on the estimation of the variance of an unbiased estimator of population mean forh= 2 are also

摘要:

AbstractThe model considered is a two‐factor cross‐classification variance components model with one observation per cell. Let the two factors beAandB, the problem is to obtain an approximate confidence interval for the ratio of variance componentAover variance componentB.In this paper, a method of solving this problem is established and simulations are performed to check the met

摘要:

AbstractBy treating the nonlinear model as if it were linear in the parameterization θ in the neighbourhood of the least squares estimate θ, we construct two‐sided nominally‐q‐prediction intervals by applying the usual linear model theory. The derivation of the truncated series expansion of the expected coverage of the prediction intervals at a feasible value of the parameter vector is described. The quadratic approximation of the expected coverage is then obtained for a two‐parameter nonlinear model. Finally we show how we may construct the prediction intervals when a certain type of nonlinear transformation of the parameter vector has bee

摘要:

AbstractFor the analysis of square contingency tables, this note proposes a multiplicative model imposed more restrictions on CAUSSINUS' (1965) quasi‐symmetry (QS) model. The model is not so strict as in the quasi‐double symmetry model considered by TOMIZAWA(1985b). The proposed model has the structure of the QS about the main diagonal plus an extended QS about the reverse diagonal of the square contingency table. The model is applied to the data on unaided vision of students in a university in Ja
