Absence of a common diagnostic interview has hampered cross-national syntheses of epidemiological evidence on major depressive episodes (MDE). Community epidemiological surveys using the World Health Organization Composite International Diagnostic Interview administered face-to-face were carried out in 10 countries in North America (Canada and the US),(More)
OBJECTIVES Current information on the prevalence of psychiatric disorders among older adults in the United States is lacking. Prevalence of anxiety, mood, and substance disorders was examined by age (18-44, 45-64, 65-74, and 75 years and older) and sex. Covariates of disorders for older adults (65 years and older) were explored. DESIGN Cross-sectional(More)
Adaptive Metropolis-Hastings samplers use information obtained from previous draws to tune the proposal distribution. The tuning is carried out automatically, often repeatedly, and continues after the burn-in period. Because the resulting chain is not Markovian, adaptation needs to be done carefully to ensure convergence to the correct ergodic distribution.(More)
Time series subject to parameter shifts of random magnitude and timing are commonly modeled with a change-point approach using Chib's (1998) algorithm to draw the break dates. We outline some advantages of an alternative approach in which breaks come through mixture distributions in state innovations, and for which the sampler of Gerlach, Carter and Kohn(More)
A Bayesian approach is presented for modeling a time series by an autoregressive-moving average model. The treatment is robust to innovation and additive outliers and identiies such outliers. It enforces stationarity on the autoregressive parameters and invertibility on the moving average parameters, and takes account of uncertainty about the correct model(More)
