Contents: NAME SYNOPSIS DESCRIPTION ALGORITHM LIMITATIONS EXAMPLES METHODS SEE ALSO AUTHOR LICENSE DISCLAIMER. NAME LineFit - Least squares line fit, weighted or unweighted. SYNOPSIS require 'linefit' lineFit = LineFit.new lineFit.setData(x,y) intercept, slope = lineFit.coefficients rSquared = lineFit.rSquared meanSquaredError = lineFit.meanSqError durbinWatson = lineFit.durbinWatson sigma = lineFit.sigma tStatIntercept, tStatSlope = lineFit.tStatistics predictedYs = lineFit.predictedYs residuals = lineFit.residuals varianceIntercept, varianceSlope = lineFit.varianceOfEstimates. DESCRIPTION The LineFit class 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 class 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. (See the METHODS section for a description of these statistics.).
