Modeling Semicontinuous Longitudinal Expenditures: A Practical Guide

A Practical Guide to Entity-Relationship Modeling

The Entity-Relationship (ER) model and its accompanying ER diagrams are widely used for database design and Systems Analysis. Many books and articles just provide a definition of each modeling component and give examples of pre-built ER diagrams. Beginners in data modeling have a great deal of difficulty learning how to approach a given problem, what questions to ask in order to build a model, ...

Bayesian Analysis for Longitudinal Semicontinuous Data

In many biomedical applications, researchers encounter semicontinuous data whereby data are either continuous or zero. When the data are collected over time the observations are correlated. Analysis of these kind of longitudinal semi-continuous data is challenging due to the presence of strong skewness in the data. In this paper, we develop a flexible class of zero-inflated models in a longitud...

Uncertainty Analysis A practical guide

During the DELPHI project a first attempt was made to standard-ise the way uncertainty analysis was carried out. However, some of the documents that were produced contain errors w.r.t. the treatment of systematic errors and could easily lead to a misinterpretation of the underlying theory. Therefore Philips Research and CQM decided to produce a document that deals with this subject in a more pr...
