摘要:

AbstractMuch attention has been given to the problem of predicting future observations for some individual within a random coefficient regression (RCR) model, using the previous observations on that individual as well as the information from the rest of the data material. In this paper, the literature on this subject is critically reviewed and new methods of linear prediction are proposed for the general RCR model. Exact results are derived for the mean squared errors of some predictors in a special case, but this is not possible in the general RCR model when its parameters are not known. In this model, the old and new predictors are compared in a simulation study, and further illustrated by prediction in a medical data material.

摘要:

AbstractRCR models are reviewed. Various variance estimators are described, among them a new one. These variance estimators are compared in a simulation study. An obstetric data set is subjected to a detailed analysis by means of RCR techniques. In particular, interval estimation is considered.

摘要:

AbstractThe problem considered is that of supplementing any given second‐order rotatable designDOwith additional design points in order to gain maximal increase in efficiency when the experimenter is allowed to double the number of design points subject to the condition that the composite design, consisting ofDOplus the additional points, should also be rotatable. Using generalized variance as a measure of efficiency some interesting results are derive

AbstractIn this note we outlined the procedure to obtain upper tail percentage points of the distribution of the average ofkindependent sample correlation coefficient (r) each of which is based onnpairs of observations. Null distribution ofrdemonstrates its application to medical research.

摘要:

AbstractIt is shown that for the one‐way analysis of covariance model with one covariate, when the hypothesis of a common slope parameter has been rejected, the Johnson‐Neyman procedure results in a confidence interval equivalent to that obtained using Fieller's theorem. It is noted in Fieller's paper that the theory behind this technique was first introduced by Bliss, but not specifically applied to the analysis of covariance problem. Credit for this procedure should be shared by Bliss, Fieller, and Johnson and Ney
