bibd: Balanced incomplete block design for given parameters

Description

This function generates a balanced incomplete block design with given number of treaments(v), number of blocks(b), number of replications (r), block size(k) and number of concurrences (lambda).

Usage

bibd(v,b,r,k,lambda,ntrial,pbar=FALSE)

Value

v

number of treatments

b

number of blocks

r

number of replications

k

block size

lambda

number of concurrences

design

block contents in a b by k matrix

N

treatments by blocks incidence matrix of the generated design

NNP

concurrence matrix of the generated design

Aeff

Lower bound to the A-efficiency of the generated design

Deff

Lower bound to the D-efficiency of the generated design

Arguments

v

number of treatments

b

number of blocks

r

number of replications

k

block size

lambda

number of concurrences

ntrial

number of trials

pbar

logical value indicating whether progress bar will be displayed or not. Default is FALSE
