Converting Data to Functions
In our discussions up to this point we appear to have assumed that functions would always be available when we need them, and we merely need to know what to do with them. Upon reflection it is apparent that this is not correct. In any application which you may face you will be required to furnish the functions. Much of the time you may have data, perhaps obtained in a laboratory or from a questionnaire, and you need a function that will describe the data. It will be our purpose in this chapter to consider this matter and to find some techniques that will be helpful. You should be aware, however, that one needs to know the discipline from which the data is obtained in order to obtain the best possible function in any given case.
