Zusammenfassung: A new linear regression method is presented for fitting the von Bertalanffy growth function to data on size at age, which is also applicable to tag and recapture data. From tests on simulated data the method shows lower error and bias and more flexibility of action than other commonly used methods.

Krivan, V., & Seda, J. (1989). Application of a guaranteed regression model to trophic interaction in an aquatic system (Vol. 49).
Zusammenfassung: The method of guaranteed estimation is used to estimate the unknown parameters of two nonlinear regression models. The first describes the relations between the body size structure of zooplankton and the biomass of planktivorous fish. The second estimates time-lag between the dynamics of cladoceran egg production and dynamics of phytoplankton.

Zusammenfassung: Prager and Hoenig (in press) used a randomization procedure to test the significance of discrete environmental events, such as el Nino-Southern Oscillation events, on a time series of recruitment. Their procedure implicitly accounted for autocorrelation and other problems frequently encountered when trying to use a parametric testing procedure. In a follow up paper, Prager and Hoenig (in prep.) investigated the power of several randomization tests and compared them to parametric alternatives. This report presents the two Fortran computer programs used in these studies.
