Sequential selection procedures: Using sample means to improve efficiency
Two-stage selection procedures have been widely studied and applied to determine appropriate sample sizes for selecting the best of k designs. However, standard “indifference-zone” procedures are derived with a statistically conservative least-favorable-configuration assumption. The Enhanced Two-Stage Selection (ETSS) is a procedure that takes into account not only the variance of samples but a...
متن کامل1979: Sequential Sample Selection Methods
Sequential sample selection methods are distinguished from conventional methods in the manner in which random numbers are used to determine the sample. Conventionally, a sample of size n is selected from a sampling frame of N sampling units by selecting n random numbers and mapping then into n of the labels in the sampling frame. Sequential methods require each sampling unit in the sampling fra...
متن کاملFully Sequential Selection Procedures with Parabolic Boundary
We present two fully sequential indifference-zone procedures to select the best system from a number of competing simulated systems when best is defined by maximum or minimum expected performance. These two procedures have parabola shaped continuation regions rather than triangular continuation regions employed in several papers. The procedures we present accommodate unequal and unknown varianc...
متن کاملFully Sequential Selection Procedures with Control Variates
Fully sequential selection procedures have been developed in the field of stochastic simulation to find the simulated system with the best expected performance when the number of alternatives is finite. Kim and Nelson proposed the KN procedure to allow for unknown and unequal variances and the use of common random numbers. KN approximates the raw sum of differences between observations from two...
متن کاملSequential Sampling with Economics of Selection Procedures
S sampling problems arise in stochastic simulation and many other applications. Sampling is used to infer the unknown performance of several alternatives before one alternative is selected as best. This paper presents new economically motivated fully sequential sampling procedures to solve such problems, called economics of selection procedures. The optimal procedure is derived for comparing a ...
