Journal of Financial Economics, 2017
We construct a robust stochastic discount factor (SDF) that summarizes the joint explanatory power of a large number of cross-sectional stock return predictors. Our method achieves robust out-of-sample performance in this high-dimensional setting by imposing an economically motivated prior on SDF coefficients that shrinks the contributions of low ...

Cross-sectional echocardiography

British Medical Bulletin, 1989
Cross-sectional echocardiography has become an essential part of the investigation of infants and children with heart disease. Frequently, it provides a precise diagnosis. In many instances, particularly in neonates and infants, surgery can be undertaken without the need to proceed to cardiac catheterisation.

Multicollinearity in cross-sectional regressions

Journal of Geographical Systems, 2006
The paper examines robustness of results from cross-sectional regression paying attention to the impact of multicollinearity. It is well known that the reliability of estimators (least-squares or maximum-likelihood) gets worse as the linear relationships between the regressors become more acute.
