Abstract

This study proposes an estimator of the correlation coefficient for a bivariate normal distribution with missing data, via the complete observation analysis method. Evaluation of the proposed estimator (ˆρ J) in comparison with the Pearson correlation coefficient (ˆρP ) was conducted using a simulation study. It was found that, for a higher percentage of missing data in a large sample size, the absolute bias of ˆρ J was less than that of ˆρ P when the population correlation coefficients (ρ) were not close to zero. In addition, the mean square error of ˆρJ was not different from that of ˆρP in each situation.
