On the Structure of Incomplete Block Designs

Calcutta Statistical Association Bulletin, 1981
The bounds for the number of treatments common to any set of blocks of a connected (v, b, r, k) design are derived, and earlier published results are shown to be inferior. A new interesting result on dual of a connected (v, b, r, k) desian is obtained.

The efficiency of blocking in incomplete block designs

Biometrika, 1960
1. Summary. Procedures for estimating the relative efficiency of certain designs have been considered by Yates (1935), Cochran & Cox (1957), and Kempthorne (1952, 1955). In this paper the efficiency of blocking in general is considered. A general formula for any incomplete block design of fairly general form is obtained. 2. Introduction.

On Multidimensional Incomplete Block Designs

Calcutta Statistical Association Bulletin, 1984
In this communication, methods of construction of balanced multidimensional incomplete block designs have been developed. Some illustrations have been presented to introduce the technique in case of four dimensional design. Multidimensional Partially Efficiency Balanced (PEB) design has been defined with suitable illustration in the concluding section.

Incomplete Split‐Block Designs

Biometrical Journal, 1997
AbstractThe paper deals with modelling of experiments carried out in incomplete split‐block designs. Moreover, the characterization of the design with respect to a general balance property is given. Also, some statistical properties of the design are examined. The problems considered are illustrated with examples.

Balanced Incomplete Block Designs with Block Size 7

Designs, Codes and Cryptography, 1998
This paper makes considerable progress in fully determining the spectrum of balanced incomplete block designs (BIBDs) with block size \(k = 7\). This work was begun by \textit{H. Hanani} [Balanced incomplete block designs and related designs, Discrete Math. 11, 255-369 (1975; Zbl 0361.62067)] and continued by \textit{A. E. Brouwer, A.

Preconditioning by incomplete block elimination

Numerical Linear Algebra with Applications, 2000
Summary: The recursive construction of Schur complements is used to construct a multi-level preconditioner for an iterative linear solver. For each level, the removed unknowns are selected in such a way that the eliminated matrix block is strictly diagonally dominant.

Incomplete Block Designs

2017
When a block design is needed for controlling the effects of nuisance factors, but the blocks cannot be made sufficiently large to accommodate all the treatments, incomplete block designs can be used instead. Basic design issues of block size, connectedness, and randomization are discussed in this chapter.

Partial Diallel Crosses in Incomplete Blocks

Biometrics, 1995
Various forms of diallel crosses play an important role in evaluating the breeding potential of genetic material in plant and animal breeding (e.g., Hinkelmann, 1975, inA Survey of Statistical Design and Linear Models, 243-269. Amsterdam: North Holland).

Incomplete Block Designs

2009
In many situations the number of treatments to be compared is large. Then we need large number of blocks to accommodate all the treatments and in turn more experimental material. This may increase the cost of experimentation in terms of money, labor, time etc.
