CombS {CombinS} | R Documentation |
The application of the Combinatory Method (s), with s chosen in [2, l-1],
on rectangular association scheme to obtain the configuration and the
parameters of the PBIB
design associated.
CombS(n, l, s)
n |
Number of lines of the association schemes array. |
l |
Number of columns of the association schemes array. |
s |
Number of the token treatments from the same row of the association scheme. |
For 2 < s < l, we obtain a rectangular PBIB design.
For s = l, we obtain a singular group divisible designs.
A LIST :
PBIB
The configuration of the PBIB.
Type
The type of the design
V
Number of treatments.
B
Number of blocs.
R
Repetition of each treatment.
K
Size of blocs.
lamda
Vector of m-lambda.
Resolvable
Is the design Resolvable ?
