exponential family existence of maximum likelihood estimate BarndorffNielsen completion
2009/9/16
When in a full exponential family the maximum likelihood estimate (MLE) does not exist, the MLE may exist in the Barndorff-Nielsen completion of the family. We propose a practical algorithm for findin...
