GROW is part of a user-friendly dialogue system CADEMO. It consists of three parts: (1) Model choice: By help of a set of data one out of ten models can be selected which fits best with the data. The user can choose one of the criteria: - residual variance - Akaike criterium - Mallows criterium - Schwartz criterium The three latter contain a penality function for the number of parameters in the model. (2) Parameter estimation and analysis. By help of the data the model parameters can be estimated (point and interval estimation). Hyited. (3) Experimental design. The sample size needed for a needed precision and an optimal allocation of future measurements can be obtained. The optimal allocation may be due to one of the optimality criteria: - minimum size of a confidence region - minimum variance of the estimate of one of the parameters.
