Abstract

This publication describes a computer program designed for analysis of surfaces using double Fourier series. Analysis of surfaces in geology is known commonly as trend analysis; in statistics and economics, the technique is regarded as a form of regression analysis. In trend or regression analysis, a mathematical function is fitted to data points so that the function satisfies the least-squares criterion, which is a criterion of "best" fit.
