A MATLABTM Code to Perform Weighted Linear Regression with (correlated or uncorrelated) Errors in Bivariate Data

Abstract

Abstract MATLABTM is a powerful, easy to use, software package suitable for many mathematical operations, which finds plenty of scientific applications. One such application is the fitting of trend lines for a given data set so as to interpret the relationship of the variance of the parameters involved. We provide here a code in MATLABTM that performs the weighted linear regression with (correlated or uncorrelated) errors in bivariate data which can handle 'force-fit' regression as well.
