ibdtvc: incomplete block design for test vs control(s) comparions

Description

This function generates incomplete block design for test vs control(s) comparisons with specified parameters and concurrence matrix.

Usage

ibdtvc(v1,v2,b,k,NNPo,ntrial)

Arguments

v1

number of test treatments

v2

number of control treatments

b

number of blocks

k

NNPo

desired concurrence matrix

ntrial

number of trials

Value

• v1=v1,v2=v2,b=b,k=k,design=design,N=N, NNP=NNP,Aeff=Aeff)
• v1
  number of test treatments
• v2
