blocksdesign (version 1.8)

efficiencies: Efficiencies of pairwise differences.

Description

Tabulates the efficieny of pairwise treatment difference for each stratum of a design constructed by blocks.

Usage

efficiencies(Design)

Arguments

Design

a design data frame generated by blocks.

Value

• Efficiencies
  List of treatments efficiency matrices for all pairwise differences for each stratum of the design

Details

Tabulates the efficiency factors of the pairwise treatment differences in every statum of any design built by the blocks function. For equi-replicate block designs, the harmonic mean of the pairwise efficiency factors will equal the A-efficiency factor.

Examples

# 4 replicates of 50 treatments in complete randomized blocks
efficiencies(blocks(treatments=50,replicates=4,blocklevels=c(4,5))$Design)
