Request: Absolute difference of proportions for a 2x2 table
Posted: Fri Nov 09, 2018 6:57 am
Hi,
I would love to see, in addition to the odds ratio, the absolute difference of (column) proportions for a 2x2 table, with its confidence interval. This effect estimate is also relevant in many studies and its inverse can be used to estimate the number needed to treat.
Should be easy to capture the output of prop.test
Thanks
Victor
