Mixtures of t-distributions for finance and forecasting [PDF]

open access: yesJournal of Econometrics, 2008
We explore convenient analytic properties of distributions constructed as mixtures of scaled and shifted t-distributions. Particularly desirable for econometric applications are closed-form expressions for antiderivatives (e.g., the cumulative density function). We illustrate the usefulness of these distributions in two applications.

Modelling Agent Forecast Distributions

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1992
SUMMARY Problems in the analysis and interpretation of uncertain inferences obtained from individuals, or agents, are considered in the context of forecasting a scalar random quantity. Based on new theoretical results presented by West and Crosse, Bayesian updating is developed for cases in which agents' opinions are provided in terms of

Forecasting and Conditional Projection Using Realistic Prior Distributions [PDF]

open access: yesEconometric Reviews, 1983
This paper develops a forecasting procedure based on a Bayesian method for estimating vector autoregressions. We apply the procedure to 10 macroeconomic variables and show that it produces more accurate out-of-sample forecasts than univariate equations do.

Quantile forecasts of daily exchange rate returns from forecasts of realized volatility [PDF]

open access: yes, 2008
Quantile forecasts are central to risk management decisions because of the widespread use of Value-at-Risk. A quantile forecast is the product of two factors: the model used to forecast volatility, and the method of computing quantiles from the ...

Utility of Computed Tomography Surveillance of Asymptomatic Infection in Children and Young Adults Before Allogeneic Hematopoietic Stem Cell Transplant

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Asymptomatic infection poses a significant risk for children undergoing hematopoietic stem cell transplantation (HSCT). Pre‐transplant surveillance computed tomography (CT) is commonly used to identify occult infection, though its diagnostic yield remains uncertain.
