Bayesian Pearson Correlation Analysis
In studies with two continuous variables usually named the x-values and y-values a linear relation between the two variables can be assessed with the help of the Pearson correlation coefficient R. R is a measure of strength of association, and varies from −1 to +1. Instead of a traditional Pearson correlation analysis a Bayesian analysis of linear correlation is possible.
A traditional analysis of Pearson linear correlation analysis provided an r-value of 0.483 with an F statistic of 10047, p-value 0.003. A Bayesian Analysis of Pearson linear correlation provided support in favor of the traditional test with a Bayes factor of 0.105.
This was less wide than the 95% confidence interval of the traditional Pearson linear correlation which was
Thus, the Bayesian analysis provided slightly better statistics than did the traditional Pearson correlation analysis.
