blocksdesign (version 3.2)

upper_bounds: Efficiency bounds

Description

Finds upper A-efficiency bounds for regular block designs.

Usage

upper_bounds(n, v, b)

Arguments

n

the total number of plots in the design.

v

the total number of treatments in the design.

b

the total number of blocks in the design.

Details

Upper bounds for the A-efficiency factors of regular block designs (see Chapter 2.8 of John and Williams 1995). Non-trivial A-efficiency upper bounds are calculated for regular block designs with equal block sizes and equal replication. All other designs return NA.
