Partially Balanced Incomplete Block Designs

open access: yes, 1969
In balanced incomplete block designs, each pair of treatments is compared with equal precision, and each treatment is paired with every other treatment an equal number of times with in a common block; A is a constant for all treatments. There is one associate class for each treatment in balanced incomplete block designs.

An Inequality for Balanced Incomplete Block Designs

open access: yesThe Annals of Mathematical Statistics, 1961
For a resolvable balanced incomplete block design, R. C. Bose [1] obtained the inequality $b \geqq v + r - 1$, and P. M. Roy [2] and W. F. Mikhail [3] proved this inequality without the assumption of resolvability, but with the weaker assumption that $v$ is a multiple of $k$. In this note an alternative and simpler proof of Roy's theorem is given.

An Inequality for Balanced Incomplete Block Designs

open access: yesThe Annals of Mathematical Statistics, 1960
The inequality $b \geqq v + r - 1$ for a balanced incomplete block design was proved by Bose [1] under the assumption of resolvability. In this note the inequality is proved without that assumption, but with the weaker assumption that $v = nk$.

A Note on Balanced Incomplete Block Designs

open access: yesThe Annals of Mathematical Statistics, 1969
Summary: The author studies balanced incomplete block designs (BIBD) in which the blocks are not necessarily distinct. He proves the following Theorem. Let \(\mathcal D\) be a BIBD with parameters \(v,b,r,k,\lambda\). If \(s\) blocks of \(\mathcal D\) are identical and if \(r>\lambda\), then \(r/k=b/v\ge s\). The theorem implies the results of E.

Construction of Rotatable Designs Through Balanced Incomplete Block Designs

open access: yesThe Annals of Mathematical Statistics, 1962
Rotatable designs were introduced by Box and Hunter (1954, 1957) for the exploration of response surfaces. They constructed these designs through geometrical configurations and obtained several second order designs. Afterwards, Gardiner and others (1959) obtained some third order designs through the same technique for two and three factors and a third ...

Balanced Incomplete Block Designs and Tactical Configurations

open access: yesThe Annals of Mathematical Statistics, 1955
A balanced incomplete block design (BIB design) is an arrangement of $v$ varieties of treatments in $b$ blocks of $k$ distinct varieties each, so that each variety is contained in $r$ blocks and every pair of varieties is contained in $\lambda$ blocks. Various methods of constructing such designs are discussed in [2], and certain designs are listed in [
