In: http://reference.wolfram.com/mathematica/RegressionCommon/ref/DurbinWatsonD.html it says that: "As of Version 7.0, DurbinWatsonD has become a property of LinearModelFit". But, when I evaluate: data = {{0.05, 90}, {0.09, 95}, {0.14, 110}, {0.17, 125}, {0.2, 140}, {0.21, 150}, {0.23, 175}, {0.25, 190}, {0.3, 210}, {0.35, 255}}; LinearModelFit[data, {1, x^2}, x, RegressionReport -> {DurbinWatsonD}] the above line will not produce the DurbinWatsonD value of 1.14 shown in the example on that web page. How can I then get the DurbinWatsonD value? Thank you! Gilmar Rodriguez Pierluissi
