Least-squares fitting of a straight line york
NettetEarlier least squares treatments of the fitting of a straight line when both variables are subject to crrors are generalized to allow for correlation of the z and y errors. The … NettetLeast Square is the method for finding the best fit of a set of data points. It minimizes the sum of the residuals of points from the plotted curve. It gives the trend line of best fit to a time series data. This method is most widely used in time series analysis. Let us discuss the Method of Least Squares in detail. Table of content.
