The expectation of a function of random variables can be modeled as the value of the function in the mean value of the variables plus a penalty term. Here, this penalty term is calculated exactly, and the properties of different approximations are analyzed. Then, a deterministic algorithm for minimizing the expected error of a feedforward network of random weights is presented. Given a particul...

This paper uses a fully nonparametric approach to estimate efficiency measures for primary care units incorporating the effect of (exogenous) environmental factors. This methodology allows us to account for different types of variables (continuous and discrete) describing the main characteristics of patients served by those providers. In addition, we use an extension of this nonparametric appro...

So called “auxiliary variables”' are often used in reasoning about concurrent programs. They can be useful but they can also be undesirable in that they can undermine the hard won property of “compositionality”. This paper explores the issue of auxiliary variables and tries to set concerns about overuse in a wider context; it concludes with an attempt to recommend constraints on their use. © 20...

When there are interactions among the independent variables, the performances of the most often used multiple regression models and ridge regression model are not well enough. In contrast, the Choquet integral takes into account the interactions among independent variables, the discrete Choquet integral regression models based on some non-negative valued fuzzy measures or monotonic measure can ...

The present study investigated variables related to errors in predicting when tasks will be completed. Participants (N = 184) responded to the Time Structure Questionnaire (TSQ; Jones, Banicky, Pomare, & Lasane, 1999) and Temporal Orientation Scale (TOS; Bond & Feather, 1988) and predicted when they would complete either a desirable or undesirable task. Factor analysis of the TSQ and TOS identi...

Life events are associated with relapse in schizophrenia. However, the role and interplay of marriage and social support have not been explored in research on schizophrenia, especially stable patients. Life events and social support were assessed in two groups comprising 30 married and an equal number of unmarried patients of schizophrenia. The time frame for these assessments was a period of 6...

In this paper, I propose that the availability of a bound variable reading for pronouns is predictable from their morphological structure of the pronouns. More specifically I argue that noun-containing pronouns cannot be bound variables. My proposal is different from D&W's (2002) argument in that in their theory, every DPs cannot have a bound variable reading, while in my theory, even DPs can h...
