fiterror | compute two-sided, asymmetric error bars for a chi^2 fit |

JWCURVEFIT | Non-linear least squares fit to a function of an arbitrary number of parameters. The function may be any non-linear function. If available, partial derivatives can be calculated by the user function, else this routine will estimate partial derivatives with a forward difference approximation. |

mpsteppar | plot 1D or 2D chi^2 contours for chi^2 fitting error determination |
