Optimal Designs for Two-level Factorial Experiments with Binary Response
We consider the problem of obtaining locally D-optimal designs for factorial experiments with qualitative factors at two levels each with binary response. Our focus is primarily on the 2 experiment. In this paper, we derive analytic results for some special cases and indicate how to handle the general case. The performance of the uniform design in examined and we show that this design is highly...
متن کاملDesigning Two-level Fractional Factorial Experiments in Blocks of Size Two
We need extra runs to design two-level factorial experiments in blocks of size two to estimate all the available effects, as is possible in experiments without blocking. The number of runs suggested is (n − p)2n−p for 2n−p fractional factorial experiments. In designing such an experiment, two issues need to be considered. First, the precision of estimates is usually different because different ...
متن کاملDesign and Analysis of Two-Level Factorial Experiments With Partial Replication
In a two-level factorial experiment, we consider construction of parallel-flats designs with two identical parallel flats that allow estimation of a set of specified possibly active effects and the pure error variance. A set of sufficient conditions is presented for the designs to be D-optimal for the specified effects, assuming that the other effects are negligible, over the class of competing...
متن کاملIdentification of dispersion effects in replicated two-level fractional factorial experiments
Tests for dispersion effects in replicated two-level factorial experiments assuming a location-dispersion model are presented. The tests use individual measures of dispersion which remove the location effects and also provide an estimate of pure error. Empirical critical values for two such tests are given for two-level full or regular fractional factorial designs with 8, 16, 32 and 64 runs. Th...
متن کاملTwo-Stage Controlled Fractional Factorial Screening for Simulation Experiments
Factor screening with statistical control makes sense in the context of simulation experiments that have random error, but can be run automatically on a computer and thus can accommodate a large number of replications. The discrete-event simulations common in the operations research field are well suited to controlled screening. In this paper two methods of factor screening with control of Type...
