GPBIB7A {CombinS}

Generalized rectangular right angular (7) design with \lambda_{i} equal to \lambda_{i+4} (i=1,...,4)

Description

gives the configuration and the parametres of the design obtained by the first construction method of GPBIB_7 (see 3.3.1 of the paper rezgui et al (2015))

Usage

GPBIB7A(n, l, s, w)

Arguments

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.

w

Number of the association scheme arrays.

Value

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.

• lambda Vector of m-lambda.

• Resolvable Is the design Resolvable ?

Note

For w=2, the GPBIB_7 is a rectangular right angular (7) (PBIB_7).
