GPBIB4A {CombinS}

Generalized rectangular right angular (4) design with \lambda_4 = 0

Description

Gives the configuration and the parametres of the design obtained by the first construction method of GPBIB_4 (see 3.1.1 of the paper rezgui et al (2015)).

Usage

GPBIB4A(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.

Details

• For s = l, the previous method gives configuration of nested group divisible designs.

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.

• lamda Vector of m-lambda.

• Resolvable Is the design Resolvable ?

Note

For w=2, the GPBIB_4 is a rectangular right angular (4) (PBIB_4)
