This web page contains list of Lattice designs.
These designs have been constructed using various methods available in the
literature, compiled and made online for easy accessibility of the
experimenters. The number of treatments (v), number of blocks (b), number of replications
(r), block size (k) and average efficiencies along with the layout of
these designs have been presented
for v up to 150 and r not exceeding 10.
Lattice designs form an important class of
incomplete block designs which provide flexibility to suit various experimental
situations. As these designs are
resolvable, replications can be taken over
space or over time. An added advantage of these designs is that these designs
may be adopted where less number of replications are feasible due to resource
constraints. Some of these are Balanced
Incomplete Block (BIB) designs while others are Partially Balanced Incomplete
Block (PBIB) designs.
The steps for
(using SPSS & SAS) have also been described.
