There exists a small sample bias in predictive regressions, when a rate of return is regressed on a lagged stochastic … regressor, and the regression disturbance is correlated with the regressors' innovations. Although this bias can be a serious … level data, we document that as the number of cross sections used in the panel data increases the bias in coefficient …

There are many real-world situations in which complex interacting forces are best described by a series of equations. Traditional regression approaches to these situations involve modeling and estimating each individual equation (producing estimates of "partial derivatives") and then solving the...

We provide a new definition of breakdown in finite samples with an extension to asymptotic breakdown. Previous definitions center around defining a critical region for either the parameter or the objective function. If for a particular outlier constellation the critical region is entered,...
