## Contents

For nonlinear least squares fitting to a number of unknown parameters, linear least squares fitting may be applied iteratively to a linearized form of the function until convergence is achieved. Standard deviation can be defined for any distribution with finite first two moments, but it is most common to assume that the underlying distribution is normal.
