This paper extends the approximate closed-form intertemporal capital asset pricing model of Campbell (1993) to allow for stochastic volatility. The return on the aggregate stock market is modeled as one element of a vector autoregressive (VAR) system, and the volatility of all shocks to the VAR...

Modern society depends on software systems of ever-increasing scope and complexity in virtually every sphere of human activity, including business, finance, energy, transportation, education, communication, government, and defense. Because the consequences of failure can be severe, dependable...

Several valuable data sources, including the census and National Longitudinal Survey of Youth, include data measured using interval responses. Many empirical studies attempt estimation by assuming the data correspond to the interval midpoints and then use OLS or maximum likelihood assuming...

The small sample performance of least median of squares, reweighted least squares, least squares, least absolute deviations, and three partially adaptive estimators are compared using Monte Carlo simulations. Two data problems are addressed in the paper: (1) data generated from non-normal error...
