Block designs for symmetric parallel line assays with block size odd
نویسندگان
چکیده
SUMMARY. In a parallel line assay, there are three treatment contrasts of major importance. Block designs allowing the estimability of all the three contrasts free from block effects, called L-designs, necessarily have the block sizes even. For odd block sizes, we provide here a class of highly efficient designs, called nearly L-designs. These nearly L-designs have been constructed by establishing a link with linear and nearly linear trend-free designs.

Incomplete Block Designs for Multiple Asymmetric Parallel Line Assays
A method of construction of A-optimal binary block designs for multiple asymmetrical parallel line assays has been proposed. Illustration of the method with examples has been provided. By this method two series of designs are obtained. The first series of designs have equal replication of treatments with unequal block sizes. The second series of designs have equal block sizes with unequal repli...
متن کاملBalanced nested designs and balanced arrays
Balanced nested designs are closely related to other combinatorial structures such as balanced arrays and balanced n-ary designs. In particular, the existence of symmetric balanced nested designs is equivalent to the existence of some balanced arrays. In this paper, various constructions for symmetric balanced nested designs are provided. They are used to determine the spectrum of symmetric bal...

متن کاملUniformly resolvable designs with index one and block sizes three and four - with three or five parallel classes of block size four
Each parallel class of a uniformly resolvable design (URD) contains blocks of only one block size. AURDwith v points andwith block sizes three and fourmeans that at least one parallel class has block size three and at least one has block size four. Danziger [P. Danziger, Uniform restricted resolvable designs with r = 3, ARS Combin. 46 (1997) 161–176] proved that for all v ≡ 12 (mod 24) there ex...
متن کاملVariations on the Dembowski-Wagner theorem
Let D be a symmetric design admitting a null polarity such that either all singular lines, or all nonsingular lines, have size (v − λ)/(k − λ); assume that this number is greater than λ in the case of singular lines. Then D is either a projective space or an orthogonal symmetric design. © 2003 Elsevier Ltd. All rights reserved. The Dembowski–Wagner Theorem [3] characterizes projective spaces as...
