Description A computer program has
been developed to construct all Hadamard
matrices up to order 1000 for which construction
methods are known. Eight methods have been
implemented to generate Hadamard matrices.
The methods are implemented as a library so that
it can be used by any other program. A front-end
program is being developed in Visual Basic for
the benefit of general users. Supersaturated
designs satisfying some measures of goodness
have been generated using resolvable orthogonal
arrays of strength two and Hadamard matrices.
Micro-array experiments are conducted to
study the relative expression level of thousands
of genes simultaneously. In these experiments,
four experimental factors are array (A), dye (D),
variety (V) and gene (G). For the experimental
situations where the same set of genes are
spotted on each array, gene/ gene specific effects
(G, AG, DG, VG) are orthogonal to global effects
(A, D, V). Optimality aspects of those designs
have been studied leaving gene specific effects
from the model.
The catalogues of all efficient block designs
and row-column designs obtained and the best
available designs have been prepared along with
their lower bounds to A- and D-efficiencies under
fixed/ mixed effects models and robustness
status.
