Asymptotic properties of model selection criteria for high-dimensional regression models are studied where the dimension of covariates is much larger than the sample size. Several sufficient conditions for model selection consistency are provided. Non-Gaussian error distributions are considered and it is shown that the maximal number of covariates for model selection consistency depends on the ...

This review has focused on only two common structural malformations. However, the difficulties and successes encountered while attempting to elucidate the genetic contribution to these two conditions are likely to be echoed in studies of other complex congenital anomalies. As our understanding of the mechanisms which give rise to a particular malformation gradually unfolds, the importance of a ...
