The parameter resolution of lsqcurvefit at different power law index, under the perturbation of Gaussian noise and power law noise and the distinguishing criterion in SVM classification; . (a) The relationship between absolute error and power law indexes under the perturbation of Gaussian noise and power law noise. The power law index ranged from 1.8 to 3. (b) The relationship between absolute error and power law indexes under the perturbation of Gaussian noise and power law noise. The power law index ranged from 1.8 to 10.
