Least squares line fit, weighted or unweighted

The StatisticsLineFit module does weighted or unweighted least-squares line fitting to two-dimensional data y = a + b * x. This is also called linear regression. In addition to the slope and y-intercept, the module can return the square of the correlation coefficient R squared, the Durbin-Watson statistic, the mean squared error, sigma, the t statistics, the variance of the estimates of the slope and y-intercept, the predicted y values and the residuals of the y values.
