Development of Phenomenological Fitting Procedure for the Fast Microcomputer
Abstract
Currently available fitting techniques for both linear and nonlinear models are slow, require expensive equipment that is not widely available, and shield the modeler from an in-depth understanding of the fitting procedure. New high speed microcomputer technology has opened the door for development of microcomputer based fitting techniques that eliminate some of these shortcomings. This paper begin by discussing fitting in general with an emphasis on the distinction between the linear fitting problem and the non-linear fitting problem. The suitability of existing fitting techniques to handle these fitting problems is analyzed, and the strengths and weaknesses of each technique are noted. A case is made to justify the development of a microcomputer based phenomenological fitting procedure, and the technique is developed. The various stages in the development of the technique are described including the arrangement of a user-friendly display, the choice and testing of the cybernetic interface, and the writing of the computer code in Turbo Pascal 5.5. The technique is validated by fitting a number of real world data sets, and two of these validation tests are discussed in detail. Finally, speculation is made about the future of the phenomenological fitting technique. The phenomenological fitting algorithm developed in the paper is included on disk with a brief user's manual.
