Abstract:
|
A likelihood-based approach with numerical approximation for synthesizing correlation coefficients is studied. The maximum likelihood estimator (MLE) and the likelihood interval are used for inference. The least squares approach is used to estimate a log-likelihood function by a function from a space of B-splines having desirable mathematical properties. This approach can be easily extended to the realm of meta-analysis involving sample correlations from different, independent studies by use of a combined likelihood function. The sample correlations between vitamin C intake and serum level of vitamin C from many studies are used to illustrate application of this approach. A simulation is conducted for comparison with conventional methods.
