DP-7 : Polynomial regression

Abstract

For any non linear function Y = f(x) regression may be obtained by fitting a polynomial. The general form of the polynomial regression is as given under:

Y=a0+a1X + a2X²+...............................................amXm+E

Where :

Y is the dependent variable and a0, a1, ............am are the regression coefficients. The documentation of the computer programme for polynomial regression includes the listing of the source file, data file and output file with test data and example calculations. The details of various statistics given in the programme output have also been given in the documentation.
