ABSTRACT
Before the development of digital computers, one did not have the facility to store and manipulate large data sets easily. The powerful, classical methodologies developed at that time for such data sets were founded on concepts and techniques from the calculus. Basically, these enable one to approximate discrete data by a continuous function and then to analyze the resulting continuous function. In this chapter, we will study these classical methods, but, whenever possible, we will indicate how even these can be improved by supplemental computer application.
