Scalar curvature, inequality and submanifold

open access: yes, 1973
Using an inequality relation between scalar curvature and length of second fundamental form, we may conclude that a submanifold must have nonnegative (or positive) sectional curvatures. An application to compact submanifolds in obtained.

CR STATISTICAL SUBMANIFOLDS

open access: yesCR STATISTICAL SUBMANIFOLDS
The non-existence of CR submanifolds of maximal CR dimension with umbilical shape operator in holomorphic statistical manifolds is proven. Our results are a generalization of the known results in the theory of CR submanifolds in complex space forms.

Statistical Policy Working Paper 18. Data Editing in Federal Statistical Agencies

open access: yes
The subcommittee on Data Editing in Federal Statistical Agencies was formed in 1988 to document, profile, and discuss the topics of data editing in Federal surveys. In preparing this report, the subcommittee walked in uncharted territory.
