### Research Grants

- STATISTICAL INFERENCE FOR SPARSE CATEGORICAL DATAAlan Agresti; Fiscal Year: 2003..The two types of improved intervals will be compared (In some cases, approximate may be better because of the inherent conservativeness of exact methods for discrete data), and extensions will be developed for stratified data. ..
