From: Comparison of two dependent within subject coefficients of variation to evaluate the reproducibility of measurement devices

(a) Technical replicate
  Affymetrix (l = 1) Amersham (l = 2)
  Estimate SE Estimate SE
μ l 2759 150.5 3.74 0.22
ρ l 0.94 0.002 0.99 0.0003
θ l 0.58 0.03 0.25 0.015
σ l 1603 17.88 0.93 0.01
ρ 12 = 0.51, Twald = 11.85, LRT = 122, PM = -7.89 (p < 0.001 for all tests) The estimate of the common WSCV under the null is 0.31 (SE = 0.014) 95% CI for (θ12): (0.28, 0.39)
