Abstract:

As has been indicated by practice, the traditional trial and error method is not an efficient tool for estimating the parameters of ecological models. The degree of complication of a typical ecological model also makes it impossible to use available formal algorithms. Two techniques can, however, be suggested which considerably improve the process of parameter estimation. One of them is the method of step by step merging subsequent state equations, and the other that of aiding the estimation process with sensitivity analysis.
