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 ...

Research in inequalities and integrals within the realm of fuzzy and interval-valued functions has advanced our understanding of uncertainty quantification and non-linear analysis. This field ...

This is a preview. Log in through your library . Abstract We introduce a general result relating "short averages" of a multiplicative function to "long averages" which are well understood. This result ...

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 ...

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 ...
