Event History Analysis in Continuous Time

2001
Event history data are obtained by observing individuals over time, focusing on times of occurrence of certain events and the types of event occurring. A review is given of event history analysis (in continuous time) based on multistate models. Examples of such models include the two-state model for survival data and the competing risks and disability ...

A Discrete-Time Method for the Analysis of Event Histories

1992
Abstract In demographic longitudinal studies, time measurements in the data are mostly reported in a rounded form: a time unit is fixed, typically a month or a year, and then the interval (of unit length) during which the event in question occurred is reported. Such rounding does cause some problems, however.

Time History Seismic Analysis

2013
In the case of design or assessment purposes the seismic capacity of the structural system should be computed for different seismic hazard levels by means of linear or nonlinear time history seismic analyses using a number of properly selected ground motions.

Bayesian analysis of the extreme value of a time history

Reliability Engineering & System Safety, 1988
Abstract This paper addresses the problem of estimating the peak factor of a stationary Gaussian process from the analysis of a single sample record of short duration. Successive extrema of the sample are ordered by decreasing magnitude and used to update the distribution of the maximum likelihood of the peak factor.

Impact of Time Granularity on Histories Binary Correlation Analysis

2019
Activities taken by students within a Virtual Learning Environment (VLE) can be represented by using binary student histories. Virtual Learning Environments allow educators to track most of the students’ individual activities that can be used to elicit the students social communities.

Time History Analysis of Steel Tall Buildings

Advanced Materials Research, 2014
The results of wind tunnel experiments were used to conduct time history analyses of three conventional square cross-section tall buildings with different structural systems. The primary purpose of the study was the direct comparison of the effects of the wind loads on the steel tall buildings.

Accuracy of Time History Analysis of Impulses

Journal of Structural Engineering, 2003
It was found that a very small time step might be needed in the step-by-step solution of the shock response from an impulse. In fact, this time step might be much smaller than the time step needed for accurate representation of the impulse and negligible period distortion.
