Odds Ratio Calculator
Odds Ratio: a planned Super Calculator tool. Covers 2 by 2 exposure by outcome counts. Stub page while the tool and its worked example are prepared. Scope is.
Odds Ratio Calculator is a planned calculator in the mathematics section of Super Calculator, covering statistics and probability.
What this calculator will compute
Inputs: 2 by 2 exposure by outcome counts, confidence level (%) and zero-cell correction toggle.
Outputs: odds ratio, confidence interval, p value and log odds ratio and its standard error.
Formula, recorded as scope and not yet verified against a primary source: OR = (a/b) / (c/d) = ad/bc from a 2 by 2 table. Confidence interval on the log scale: exp(ln(OR) plus or minus z * sqrt(1/a + 1/b + 1/c + 1/d)). Haldane-Anscombe correction adds 0.5 to every cell when any cell is zero.
