Confidence Interval Estimation for a Difference Between Two Dependent Intraclass Correlation Coefficients With Variable Class Sizes
Four confidence intervals for a difference between two dependent intraclass correlation coefficients (ICCs) are developed, focusing on applications to family studies. The basic idea adopted here is that confidence intervals for a difference between two parameters can be obtained from confidence limits for each parameter. Among the four confidence procedures considered, the one based on the inverse hyperbolic tangent transformation for a single ICC performed best. Francis Galton’s data on human stature are used to illustrate the methodology.
