Sažetak
The problem of yield estimation in plants and animal production is considered. The estimation should be done as early and as exactly as possible. For that purpose the well--known asymptotic growth models are used: general exponential model, von Bertalanffy model, logistic and generalized logistic model. In all mentioned methods the model--function y can be written in the following form: y(t ; A, p)=A g(t ; p), where A is the upper asymptote, and p is the parameter vector, which should be estimated on the basis of measurement data (t_i, y_i), i=1, ..., m. Parameter estimations will be done on the basis of the ordinary least squares method. Since the unknown parameter A in the considered models can always be separated, it is possible to apply a special parameter estimation method whose variables separate. The mentioned method of yield estimation is illustrated with several practical examples.
