Bias and Precision of the Squared Canonical Correlation Coefficient Under Nonnormal Data Condition
Monte Carlo methods were employed to investigate the effect of nonnormality on the bias associated with the squared canonical correlation coefficient (Rc 2). The majority of Rc 2 estimates were found to be extremely biased, but the magnitude of bias was impacted little by the degree of nonnormality.

15 صفحه اولRunning Head: CORRELATION COEFFICIENT NONNORMALITY 1 Reducing Bias and Error in the Correlation Coefficient Due to Nonnormality
It is more common for educational and psychological data to be non-normal than to be approximately normal. This tendency may lead to bias and error in point estimates of the Pearson correlation coefficient. In a series of Monte Carlo simulations, the Pearson correlation was examined under conditions of normal and non-normal data, and it was compared to its major alternatives, including the Spea...
