series5 {PBIBD}

This function constructs three-associate class PBIB designs.

Description

Consider a module M having m elements and there are n classes corresponding to each element of the module. Thus, we have a total of v = mn treatments (m is odd prime). For these v = mn treatments following are the parameters of the three-associate class PBIB design:

v = mn, b = mn, r = (m+n-2), k = (m+n-2)

lambda 1 = m-2, lambda 2 = 2, lambda 3 = n-2

Usage

series5(m, n)

Arguments

m

Size of Module M.

n

n is the number of classes to which the elements of Module M are assigned.

Value

The function returns the required three-associate class PBIB design with the parameters specified in the description.
