The Yield Curve and Predicting Recessions [PDF]
SSRN Electronic Journal, 2006 The slope of the Treasury yield curve has often been cited as a leading economic indicator, with inversion of the curve being thought of as a harbinger of a recession. In this paper, I consider a number of probit models using the yield curve to forecast recessions. Models that use both the level of the federal funds rate and the term spread give better

Bayesian prediction of an epidemic curve
Journal of Biomedical Informatics, 2009 An epidemic curve is a graph in which the number of new cases of an outbreak disease is plotted against time. Epidemic curves are ordinarily constructed after the disease outbreak is over. However, a good estimate of the epidemic curve early in an outbreak would be invaluable to health care officials.

Predicting unknown species numbers using discovery curves [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2007 A common approach to estimating the total number of extant species in a taxonomic group is to extrapolate from the temporal pattern of known species descriptions. A formal statistical approach to this problem is provided. The approach is applied to a number of global datasets for birds, ants, mosses, lycophytes, monilophytes (ferns and horsetails ...

Survival Model Predictive Accuracy and ROC Curves
Biometrics, 2005 SummaryThe predictive accuracy of a survival model can be summarized using extensions of the proportion of variation explained by the model, orR2, commonly used for continuous response models, or using extensions of sensitivity and specificity, which are commonly used for binary response models.
