The SAS interval functions INTNX and INTCK perform calculations with date, datetime values, and time intervals. They can be used for calendar calculations with SAS date values, to count time intervals ...

This chapter summarizes the time intervals, date and datetime informats, date and datetime formats, and date and datetime functions available in the SAS system. The use of these features is explained ...

We also obtain some additional results on smooth numbers in almost all intervals, and sign changes of multiplicative functions in all intervals of square-root length. Annals of Mathematics, a ...

Research from all publishers In recent years, significant strides have been made by introducing new classes of fuzzy-interval-valued functions and developing corresponding integral inequalities.

A simple general method is proposed for constructing confidence intervals for arbitrary functions of variance components in balanced normal-theory models. The concept of "surrogate variables" is ...
