Extension of model-based classification for binary data when training and test populations differ

Jacques, J.; Biernacki, C. - In: Journal of Applied Statistics 37 (2010) 5, pp. 749-766

Standard discriminant analysis supposes that both the training sample and the test sample are derived from the same population. When these samples arise from populations differing in their descriptive parameters, a generalization of discriminant analysis consists of adapting the classification...
