It has been suggested recently that the Department of Health and Social Security's instructions for collecting National Health Service waiting list statistics in England and Wales' contain anomalies as a result of the exclusion of several categories of patients awaiting surgery.2 The aim of this study was to quantify the anomalies in one district general hospital and to assess their effect in d...

Panel Data Models for Stock Returns: the Importance of Industries

We perform specification tests of unbalanced panel data models for stock return prediction using an estimate of the coefficient covariance matrix robust to spatial heteroskedasticity. We apply estimators of individual effects and time effects in unbalanced panel models. For a panel of 1243 US firms for the period 1985–2002 we find that industry effects are significant and interact with firm cha...

One reason for this is that it is often rather difficult to determine the total pathogen load in an infected host, parti...
