Prognostic significance of the age factor in the thyroid cancer: Statistical analysis

Journal of Surgical Oncology, 2004
AbstractBackground and ObjectivesTo determine whether thyroid carcinoma in elderly patients presents any peculiar characteristics, whether the greater biological aggressiveness of the neoplasm modifies the surgical treatment selected, and whether age greater than 70 years represents an independent prognostic factor.MethodsRetrospective analysis of case

Robustness of Statistical Inference in Factor Analysis and Related Models

Biometrika, 1987
In this paper the author considers a class of latent variable models which includes the unrestricted factor analysis model. In this class of models it is shown that normal theory tests of fit and sequential difference tests retain all their asymptotic properties when common factors are fixed or have nonnormal distributions. The minimum discrepancy test
