This chapter presents asymptotically optimal procedures for sequential adaptive selection of the best of several normal means. It is shown that for a sequential procedure based on elimination, if k, δ,{μ i} and σ 2 are fixed and P* →1, then there is a sharp asymptotic lower bound for the natural measure of efficiency.

In statistics, sequential analysis or sequential hypothesis testing is statistical analysis where the sample size is not fixed in advance. Instead data are evaluated as they are collected, and further sampling is stopped in accordance with a pre-defined stopping rule as soon as significant results are observed.

Thus a conclusion may sometimes be reached at a much earlier stage than would be.

We propose two new testing procedures, and prove that they control the false discovery rate in the ordered testing setting. We also show how the methods can be applied to model selection using recent results on p-values in sequential model selection settings.

Keywords: multiple hypothesis testing, stopping rule, false discovery rate, sequential File Size: 2MB. The advantages of sequential methods for clinical trials were also soon noticed.

In the medical context the benefits of stopping early can be ethical as well as purely economic. Bross 11 introduced sequential medical plans for comparing two sets of binary responses, and Kilpatrick & Oldham 32 applied the sequential t ‐test to a comparison of Cited by: 1.

A sequential file must be read (or written) from front to back; it is like a book whose pages can be turned in only one directionforwards. A random access file allows reads (or writes) at any place within it; it is like a normal book that can be opened to any particular page number.

Santner), Design of Experiments: Ranking and Selection (Eds. Santner and A. Tamhane), Marcel. The authors present one-sided and two-sided tests, introduce several families of group sequential tests, and explain how to choose the most appropriate test and interim analysis schedule.

Their topics include placebo-controlled randomized trials, bio-equivalence testing, crossover and longitudinal studies, and linear and generalized linear : $ procedures. Boesel et al. () and Nelson et al. () showed that their procedures can be successfully applied to very large number of systems, say systems.

Among these various remedies, we will take fully sequential ap-proach to develop efficient procedures for comparison with a standard. In this paper, we propose fully sequential. The difference between sequential gearboxes and H pattern shifts, lies mostly in the gear changing method.

Flexible Implementations of Group Sequential Stopping Rules one-to-one for a given pair of response variances, (ao, a2). When the variance is unknown, one option for incorporating variance estimates at analysis j is to fix the variance esti- mate at each prior analysis according to the statistical in.

multiple test procedures are represented by directed, weighted graphs, where each node corresponds to an elementary hypothesis, together with a simple algorithm to generate such graphs while sequentially testing the individual hypotheses.

The approach is illustrated with the visualization of several common gatekeeping strategies. For that reason, they are said to be “fully sequential with elim-ination.” The motivation for adopting fully sequential procedures is to reduce the overall simulation effort required to find the best system by eliminating apparently inferior alternatives early in the experimentation.

Extending the Welch Test to > 2 Independent Samples. That is, for all the statistics in the rejection region and in acceptance region, the SEQTEST procedure provides three different sample space orderings: the stage-wise ordering uses counterclockwise ordering around the continuous region, the LR ordering uses the distance between the observed Z statistic, z, and its hypothetical value, and the.

THE SEQUENTIAL FILE ORGANIZATION. In this file organization, the records of the file are stored one after another both physically and logically. That is, record with sequence number 16 is located just after the 15 th record.

A record of a sequential file can only be accessed by reading all the previous records. We consider a multiple hypothesis testing setting where the hypotheses are ordered and one is only permitted to reject an initial contiguous block, H_1,\\dots,H_k, of hypotheses.

A rejection rule in this setting amounts to a procedure for choosing the stopping point k. This setting is inspired by the sequential nature of many model selection problems, where choosing a stopping point or a model Cited by: Sequential Sampling, The Sequential Probability Ratio Tcst, The Normal Case, An Example, Sequential Sampling by Attributes, An Example of Sequential Sampling by Attributes, Two-sided Tests, An Example of a Two-sided Test, Military and Civilian Sampling Systems, The Standard Procedure, Summary and discussion of: \Sequential selection procedures and false discovery rate control" Statistics Journal Club, Mattia Ciollaro and Calvin McCarter Acknowledgements: Sincere thanks to Max Grazier G’Sell for taking the time to answer our questions about the paper and for the very useful conversations.
