###### Abstract

For the given data $(p_i,t_i,f_i),$ $i=1,\ldots,m$, we consider the

existence problem of the best parameter approximation of the exponential model function in the sense of ordinary least squares and total least squares.

Results related to that problem which have been obtained and published by the authors so far are given in the paper, as well as some new results on nonuniqueness of the best parameter approximation.

###### Keywords

exponential growth model, ordinary least squares, total least quares, existence problem
