Abstract:
|
Confidence intervals ( based on F-distribution and (Z) standard normal distribution) for the difference between two intraclass correlation coefficients under unequal family sizes based on two independent multinormal samples have been proposed. It has been found that the confidence interval based on F-distribution consistently and reliably produced better results than the confidence interval based on standard normal distribution in terms of shorter average length. The coverage probability of the interval based on F-distribution is competitive with the coverage probability of the interval based on standard normal distribution. An example with real life data is presented.
