I am running a two year old notebook it does not recognize the property "MeanPredictionErrors" anymore. It is also not listed in "properties". On the otherhand "MeanPredictionConfidenceIntervalTable" gives an answer but is also not listed as properties. Did I miss something?
data = {{1., 0.75}, {2., 0.89}, {3., 0.42}, {4., 0.99}, {5., 0.84}, {6., 0.34}, {7., 0.83}, {8., 0.93}, {9., 0.76}, {10., 0.11}}; nlm = NonlinearModelFit[ data, {Exp[a + b x^2], b < -1/2}, {{a, 0}, {b, -1}}, x]
