Least squares fitting Gaussian type curve
Given the data (p_i, t_i, y_i), i=1, ..., m, m>=3, we give necessary and sufficient conditions which guarantee the existence of the weighted least squares estimate for a Gaussian type function. To this end, we suggest a choice of the suitable initial approximation for an iterative minimization, and give some numerical examples.
