Mantel haenszel odds ratio formula
WebTable 5: 4.9 Question 12 Should you compute a summary Mantel-Haenszel odds ratio for these data? Why or why not? Calculate it if you should. When should you not calculate one? Your Answer: There is no confounding present because the crude OR is less than the stratum specific OR values. Therefore, you should not compute the MH odds ratio. WebIn general, we define the cumulative odds for Y ≤ j as. F ( j) ( 1 − F ( j)) = π 1 + ⋯ + π j π j + 1 + ⋯ + π J, for j = 1, …, J − 1. with sample estimate F ^ ( j) / ( 1 − F ^ ( j)). The case j = J is not defined because 1 − F ( J) = 0. Like cumulative probabilities, cumulative odds are necessarily non-decreasing and will be ...
