Researchers have developed a new method for fractionally supervised classification (FSC) that accommodates nominated samples, which are common in applications where extreme observations are retained. This approach addresses limitations in existing FSC formulations that assume simple random sampling. The new methodology introduces a latent representation to account for class membership and the composition of remaining units, enabling a proper EM algorithm and a weighted-likelihood procedure for nominated sample data.
