Greetings, I'd appreciate any suggestions on relatively recent references to outlier detection, particularly survey articles that may review methods that are currently "state of the art". I've begun working with a number of datasets where the identification of influential observations is proving to be critical for modeling and prediction purposes. I'd especially appreciate information on methods that researchers have found useful for larger datasets, e.g., n>10,000. The data I am working with is non-Gaussian. Thanks very much. Cheers, Mark
