It is quite true that my intersubjectivity is not deduced but assumed. Using the opportunity provided by Dowe's observations, I summarize the reasons that have led me to this choice. 相似文献

Logistic regression techniques can be used to restrict the conditional probabilities of a Bayesian network for discrete variables. More specifically, each variable of the network can be modeled through a logistic regression model, in which the parents of the variable define the covariates. When all main effects and interactions between the parent variables are incorporated as covariates, the conditional probabilities are estimated without restrictions, as in a traditional Bayesian network. By incorporating interaction terms up to a specific order only, the number of parameters can be drastically reduced. Furthermore, ordered logistic regression can be used when the categories of a variable are ordered, resulting in even more parsimonious models. Parameters are estimated by a modified junction tree algorithm. The approach is illustrated with the Alarm network. 相似文献

The field of application of a result given by Singh and Vasudeva (1984, J. Indian Statist. Assoc., 22, 93–96) which provides a way of characterizing the distribution of a random variable X, through conditional distributions of a second variable Z, given X, is extended. 相似文献

Summary The conventional procedures for a common odds ratio in multiple 2×2 tables are explored and critiqued. Three types of linear
approximation to the likelihood equations under some models of common measures of association are used to derive the popular
conventional estimators and test statistics. Some of them are derived using the model of the common standardized difference
which is an unacceptable measure. The derivation provides us with some characteristics of the procedures. The advantages of
procedures based on the conditional and unconditional likelihoods are discussed.

The exact distribution of extremes of a non-gaussian stationary discrete process is obtained and their crossing intervals are studied in terms of the autocorrelation coefficients for any level of crossing. This process is an important model for some physical magnitudes. 相似文献
