The best least squares approximation problem for a 3-parametric exponential regression model

Given the data (p_i, t_i, f_i), i=1, ..., m, we consider the existence problem for the best least squares approximation of parameters for the 3-parametric exponential regression model. This problem does not always have a solution. In this paper it is shown that this problem does have a solution, provided the data are strongly increasing at the ends.
