P.  aErrors incurred when unsing iwoo's sequential decision rule in insect sampling.h[electronic resource]  c1984  aSequential decision rules based upon defining a relationship between the mean and variance of a population and using this relationship in a confidence interval about a sum of counts on sample units have been developed and used for sampling insect pests. The actual error rates that arise from the use of these rules are much larger than the nominal ones. This occursfor three reasons:The confidence interval isincorrectly used as a sequential decision rule; it is assumed that random variables are normally distributed; and variances are not constant. If these sequential decision rules are to be used, we suggest that actual error rates be determined through simulation.  aAmostragem  aInseto  aAmostragem sequencial1 aSIMMONS, G.
