Two-Phase Experimental Design Construction and Analysis
Description
Constructs and evaluates a two-phase experimental design using cyclic methods. Calculates information matrices and Canonical Efficiency Factor (CEF) under correlated error structures.
Usage
TwoPhaseDesign(v, rho, plot = TRUE)
Arguments
v |
Integer (>=3). Number of treatments in Phase II. |
rho |
Numeric (-1 < rho < 1). Correlation coefficient. |
plot |
Logical. If TRUE (default), generates a CEF plot using ggplot2. |
Value
A list containing the Phase I and Phase II layouts, combined layout, information matrices for treatment and interaction effects, and a table and plot of Canonical Efficiency Factors.
