摘要:A general form of the location and model is considered for mixed continuous and categorical variables observed in a number of different populations, and some special cases of practical interest are cited. The distance between any 2 populations is derived for each of these models. Estimation of parameters in these distance measures is discussed, and the methods are illustrated by application to previously published data.

摘要:The duality theory of geometric programming and the special methods available for solution can be used to obtain maximum likelihood estimates for multinomial probabilities. Three examples are given [for gene frequency, compounded probabilities and multinomial distribution estimation].

摘要:Kernel models are developed and applied to the problem of [human] differential diagnosis via the diagnostic paradigm. They are shown to be a useful method both in their own right and when used in conjunction with logistic analysis.

摘要:Procedures for making inference about both the mean potential that an infective has for infecting a given susceptible from the same household, and the mean potential he has for infecting a given susceptible from another household are proposed. These estimation procedures provide a check for the assumption that the disease spreads homogeneously through the community, that is the assumption of homogeneous mixing. They also provide a means of checking whether or not the spread of infection within...

摘要:An approximation to marginal rank likelihoods is given and used to make inferences for the linear regression model with censored data. The approximations involve linear rank statistics, adapted for censored data, and estimates of their variance. Various explicit scores are given for right censored data and logistic scores for doubly censored data. Inferences using the approximate rank analysis are compared with inferences using fully and partially parametric techniques on 2 data sets. [An exam...
