These two tutorial videos will show you how to filter and sort data in Base SAS. In this first video, you will learn to use a WHERE statement in Base SAS to filter or subset SAS data. Data sets can be very large and filtering data enables you to select
My daughter's middle school math class recently reviewed how to compute the greatest common factor (GCF) and the least common multiple (LCM) of a set of integers. (The GCF is sometimes called the greatest common divisor, or GCD.) Both algorithms require factoring integers into a product of primes. While helping
