Gamma Duration Models with Heterogeneity

The Review of Economics and Statistics, 1991
In the authors' analysis of nonwork spells for Workers Compensation Insurance, they use the family of generalized gamma distributions for the structural model of failure time and both nonparametric and parametric controls for heterogeneity. These specifications allow for nested likelihood tests of not only the correct form for parametric heterogeneity,

Quantitative modeling of segmental duration

Proceedings of the workshop on Human Language Technology - HLT '93, 1993
In natural speech, durations of phonetic segments are strongly dependent on contextual factors. Quantitative descriptions of these contextual effects have applications in text-to-speech synthesis and in automatic speech recognition. In this paper, we describe a speaker-dependent system for predicting segmental duration from text, with emphasis on the ...

Phone duration modeling for LVCSR

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
Modeling phone durations in a word-specific fashion has previously been shown to lead to improvements in LVCSR recognition performance. We report results on the Switchboard database which confirm that at least small improvements (around 0.2-0.3% absolute) can be obtained.

Duration Modeling for Emotional Speech

2012
Human interaction involves exchanging not only explicit content, but also implicit information about the affective state of the interlocutor. In recent years, researchers attempt to endow the computers or robots with humanity. Various affective computing models have been proposed, which covers the areas of emotion recognition, interpretation ...

A Model of Empty Duration Perception

Perception, 1987
An attempt to construct a general theory of duration perception is presented. First, four experiments are reported in which the supplement hypothesis, on the relation between two or three empty durations, was examined: the subjective duration of a subjectively empty time interval is directly proportional to its physical duration plus a constant of ~ 80

Models for Durations: A Guide to Empirical Applications in Health Economics

2014
This article provides an introduction to the application of duration models in applied health economics. It starts by presenting nonparametric methods for a descriptive analysis of micro-data. Next, more parametric models are presented that study the importance of both observed and unobserved determinants. Finally, the article discusses some extensions,

Duration models

2010
Duration models appear when studying the moment in time that certain events occur. Next to general applications in economics and medical sciences, their financial applications are in the more specific field of market microstructure (transaction times of assets or derivatives in a given market), and also in corporate governance (tenure of management).
