摘要:
Discrete frequency distributions obtained from samples of various arthropods commonly found in Texas cotton fields were fitted to 6 discrete mathematical frequency-distribution models. The observed frequency distributions most frequently fit the negative binomial expectations, suggesting a clumped pattern of dispersion. These same arthropods were seldom observed to be randomly dispersed as indicated by poor agreement with the Poisson expectations.
