balanced factorial designgeneralized cyclic designEGD‐PBIB designIn this chapter we discuss different methods of constructing systems of confounding for asymmetrical factorial designs, including: Combining symmetrical systems of confounding via the Kronecker product method, use of pseudo-factors, the method ...
An Introduction to Propensity Score Methods for Reducing the Effects of Confounding in Observational Studies. The propensity score is the probability of treatment assignment conditional on observed baseline characteristics. The propensity score allows one to design... Austin,C Peter - 《Multivariate ...
So, before arranging factorial experiment in a block design one needs to know whether the design is connected or not and what are the contrasts confounded. Bose and Kishen (1940), Bose (1947a), White and Haltquist (1965) gave a single-replicate block design where all contrasts belonging ...
In these cases the design becomes incomplete in that not every treatment is in every block. If the design is incomplete, then we immediately are faced with the fact that treatment comparisons are confounded with block effects which, of course, will cause problems. There is the obvious problem ...
A theory on constructing 2n–m designs with general minimum lower-order confounding. Statistica Sinica 21:1571–89.[Crossref], [Web of Science ] , [Google Scholar]), where 2–m denotes a two-level design with n factors and N=2nm runs. In this article, we propose a method to study ...

The method is much easier than before since the calculation only makes use of the design matrix. All 128-run GMC designs with the number of factors ranging from 8 to 32 are provided for practical use. 展开 关键词: Aliased effect-number pattern Clear Fractional factorial design GMC Minimum ...
