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.

Yamagishi, H., & Ishioka, K. (1989). Simulation study on the growth variation of fish with special reference to the sexual dimorphism in growth.
Zusammenfassung: With respect to the sexual dimorphism in growth of fish, computer simulation of individual growth variation was made in terms of coefficient of variation (CV) and skewness (sk) of frequency distribution. Normal distributions of initial body length, specific growth rate in exponential growth coefficient in asymptotic growth and asymptotic value (each consisting of 500 monosexual distributions) were supposed. In exponential growth both CV and sk of the bisexual distributions increased more quickly than the two monosexual distributions. In asymptotic growth (Bertalanffy and Logistic) CV of the bisexual distribution was always greater than the monosexual distributions, and sk of the former was greater in positive value and smaller in negative value than those of the latter all the time.
