A method for transforming rice stinkbug counts in rice

Discipline: Agriculture, Pest Management, Pest Science

Abstract:

Most statistical procedures presuppose a normal distribution, with variance independent of mean insect population. However, in field counts of a majority of insect species, variance varies as a power function of the population (Taylor 1961). Such data have to be transformed before analysis to eliminate the dependence of the variance on the mean population.
