Title
THE 2-SPRT AS AN ALTERNATIVE TO WALD'S SPRT WHEN TESTING HYPOTHESES CONCERNING INSECT POPULATIONS
Abstract
Exact and Wald's approximations for the operating characteristic and average sample number functions are compared for a sequential probability ratio (SPRT) test commonly used in cotton integrated pest management (IPM) programs in southwestern Oklahoma. The 95th percentile of the sample size is also given. For the same set of hypotheses and stated error probabilities, the exact operating characteristic and average sample number functions and the 95th percentile of sample size are compared for the SPRT and 2-SPRT.
