The Brabant Data Set, now freely accessible, contains information on a sample cohort of 3,000 individuals born around 1940 from surveys in 1952, 1983 and 1993, as well as on deaths between 1994 and 2009. In line with numerous epidemiological studies we find that among the early variables...

This technical note consists of three parts. The first describes the origins of the Brabant data set, the later surveys and the mortality data. The second section discusses the variation of mortality rates with age in the population and in the sample. The third section sets out the proportional...

This is a unique account of the role played by 58 figures and diagrams commonly used in economic theory. These cover a large part of mainstream economic analysis, both microeconomics and macroeconomics and also general equilibrium theory.

In a discrete model, the predicted probabilities of a particular event can be matched to the observed (0, I) outcomes and this will give rise to a measure of fit for that event. Previous results for the binomial model are applied to multinomial models. In these models the measure of fit will...

The discrete outcome of a probability model is recorded as Y(i)=1 while otherwise Y(i)=0. y is the vector of observed outcomes, p the corresponding probabilities, p^ a consistent estimate of p, and residuals are defined as e = y - p^. Under quite general conditions, the asymptotic properties of...

In a binary logit analysis with unequal sample frequencies of the two outcomes the less frequent outcome always has lower estimated prediction probabilities than the other one. This effect is unavoidable, and its extent varies inversely with the fit of the model, as given by a new measure that...

A bank employs logistic regression with state-dependent sample selection to identify loans that may go wrong. Inspection shows that the logit model is inappropriate. A bounded logit model with a ceiling of (far) less than 1 fits the data much better.
