The logistic regression model is used to predict a binary response variable in terms of a set of explicative ones. The estimation of the model parameters is not too accurate and their interpretation in terms of odds ratios may be erroneous, when there is multicollinearity (high dependence) among the predictors. Other important problem is the great number of explicative variables usually needed ...

The field of opinion mining has emerged in recent years as an exciting challenge for computational linguistics: investigating how humans express subjective judgments through linguistic means paves the way for automatic recognition and summarization of opinionated texts, with the possibility of determining the polarities and strengths of opinions asserted. Sentiment lexicons are basic resources ...

Market baskets arise from consumers’ shopping trips and include items from multiple categories that are frequently chosen interdependently from each other. Explanatory models of multicategory choice behavior explicitly allow for such category purchase dependencies. They typically estimate own and across-category effects of marketing-mix variables on purchase incidences for a predefined set of p...

In this paper I analyze the various factors that drive educational achievement across various countries using regression analysis. The causal model includes the variables which describe family background, learning resources, school characteristics, learning approaches, and class features to fully account for all of the features that contribute to educational achievement. The Programme for Inter...

Multiple logistic regression analyses were used to assess the associations of periodontitis and the...

This year the CUNY-BLENDER team participated in the English Entity Linking and Slot Filling Validation tracks. for entity linking, we apply two new techniques, collaborative clustering and query reformulation. For answer validation, we use a logistic regression model trained on within-system and crosssystem features to re-rank the merged answer sets generated by individual systems. In this pape...

In the task of event coreference resolution, recent work has shown the need to perform not only full coreference but also partial coreference of events. We show that subevents can form a particular hierarchical event structure. This paper examines a novel two-stage approach to finding and improving subevent structures. First, we introduce a multiclass logistic regression model that can detect s...

It has been shown that frailty is associated with low levels of well-being and life satisfaction. Further exploration is needed, however, to better understand which components constitute life satisfaction for frail older people and how satisfaction is related to other life circumstances. The aim of this study was to examine relationships between frail older people's life satisfaction and their ...
