Perhaps a note, if it says what those "issues" may be. > BTW, in researching this function I found: http://www.statemaster.com/encyclopedia/Correlational-research > It may just be a presentation issue but does the square root on the denominator extend across both of the summation signs? > Oh, the resource I cite above alleges a better way to calculate this function with numeric stability. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
