Table AOT2. Test that Lin’s concordance coefficient = K0

Power or sample size are computed based on using the approximate normality of Fisher’s z transformation of the concordance coefficient. The formula for V(Κ) was corrected in Lin, L., Hedayat, A.S., Sinha, B., Yang, M. (2002). Statistical methods in assessing agreement: models, issues, and tools. Journal of the Amer. Stat. Assn 97:257-270. See nQuery Advisor® manual Appendix for details of computing method for z. Figure AOT2 shows computations for one example. Additional values for V(Κ) and for power tested against all examples in Tables 2 and 3 from tables in Lin, L., Hedayat, A.S., Sinha, B., Yang, M. (2002). Statistical methods in assessing agreement: models, issues, and tools. Journal of the Amer. Stat. Assn 97:257-270. Checks of power to n versus n to power.
