PNBB Design of Type 2 (PNBBD 2)
Description
A block design with neighbour effects is said to be partially neighbour balanced based on m-class association scheme if two treatments 'Theta' and 'Phi' that are mutually u-th associates (u = 1, 2,…, m) appear as neighbours (left and right) 'Mu'_1u times. The design so obtained is a ((v-1)/2) associate classes partially variance balanced design following a varying circular association scheme. When v is a prime number, the function will generate a class of partially neighbour balanced block designs. 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
