|Subject: ||Binary=Interval variable?|
|Content-Type: ||text/plain; charset="us-ascii"|
Is it legitimate to always consider a binary varible (coded 0,1) an interval
variable and use the appropriate measures/tests?
For instance, if you have two binary variables is it alright to use the
Pearson correlation coefficient as a measure of association between them?
Many thanks in advance,
