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 ...

Adaptive confidence intervals for regression functions are constructed under shape constraints of monotonicity and convexity. A natural benchmark is established for the minimum expected length of ...

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.

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 ...
