| Summary : Partially Balanced t-Designs (PBtDesigns)
|
Description :
The t-designs represent a generalized class of balanced incomplete
block designs in which the number of blocks in which any t-tuple of
treatments (t >= 2) occur together is a constant. When the focus of an
experiment lies in grading and selecting treatment subgroups, t-designs
would be preferred over the conventional ones, as they have the
additional advantage of t-tuple balance. t-designs can be
advantageously used in identifying the best crop-livestock combination
for a particular location in Integrated Farming Systems that will help
in generating maximum profit. But as the number of components
increases, the number of possible t-component combinations will also
increase. Most often, combinations derived from specific components are
only practically feasible, for example, in a specific locality, farmers
may not be interested in keeping a pig or goat and hence combinations
involving these may not be of any use in that locality. In such
situations partially balanced t-designs with few selected combinations
appearing in a constant number of blocks (while others not at all
appearing) may be useful (Sayantani Karmakar, Cini Varghese, Seema
Jaggi & Mohd Harun (2021)< doi:10.1080/03610918.2021.2008436>). Further,
every location may not have the resources to form equally sized
homogeneous blocks. Partially balanced t-designs with unequal block
sizes (Damaraju Raghavarao & Bei Zhou
(1998)< doi:10.1080/03610929808832657>. Sayantani Karmakar, Cini
Varghese, Seema Jaggi & Mohd Harun (2022).\" Partially Balanced
t-designs with unequal block sizes\") prove to be more suitable for such
situations.This package generates three series of partially balanced
t-designs namely Series 1, Series 2 and Series 3. Series 1 and Series 2
are designs having equal block sizes and with treatment structures 4(t
+ 1) and a prime number, respectively. Series 3 consists of designs
with unequal block sizes and with treatment structure n(n-1)/2. This
package is based on the function named PBtD() for generating partially
balanced t-designs along with their parameters, information matrices,
average variance factors and canonical efficiency factors.
