Letters To S&C

Letters To S&C Questions on Smoothing Editor, I have recently become a subscriber to your magazine and also purchased back volumes of articles.

Is not such an analytical formula the essential conclusion of the discussion? Some show a BASIC program which can be no better than the formula it is based on. It is often far more convenient to enter formulas directly into a spreadsheet than writing a BASIC program. Maybe some of my questions warrant an article on the subject, as surely other readers must have the same questions. Specifically, here are my questions: A.
