NBB Design of Type 2 (NBBD 2)
Description
When v is odd number but not a power of a prime number (v<= 100) , the function generates a class of neighbour balanced block designs for a given number of treatments. This design listed as type 1 design (Azais, 1993) which is constructed using the method of Rees (1967) and Azais (1987). It also gives the parameters of the design, information matrix for estimating the contrast pertaining to direct and neighbour effects (both left and right) of the treatments.
Usage

Arguments
v |
Number of treatments (v is odd number but not a power of a prime number) |
Value
It generates neighbour balanced block designs for a given number of treatments (v>3), v is odd number but not a power of a prime number.
