Title:
Addition of runs to a supersaturated design
Abstract of Talk
The purpose of this presentation is to introduce a new class of
extended $E(s^2)$-optimal two-level supersaturated designs obtained by
adding runs to an existing $E(s^2)$-optimal two level supersaturated
design. The extended design is a union of two optimal SSDs belonging
to different classes. New lower bound to $E(s^2)$ has been obtained
for the extended supersaturated designs.
This idea has been further extended to obtain multi-level
supersaturated designs. Extended $E(\chi^2)$-optimal multi-level
supersaturated design has been obtained by adding runs to an existing
$E(\chi^2)$-optimal multi-level supersaturated design. The extended
design is again a union of two $E(\chi^2)$-optimal multi-level
supersaturated designs belonging to different classes. A lower bound
to $E(\chi^2)$ has been obtained for the extended supersaturated
designs. Some examples and a small catalogue of both $E(s^2)$-optimal
and $E(\chi^2)$-optimal extended supersaturated designs has been
prepared. These designs are available at www.iasri.res.in/design/.
