However it refers to 2x2 tables, that are special cases of logistic regression with a single independent variable X which is categorical and have only 2 possible values. StudyExp <- replicate(6000, simulationExp() ) ![]() fishing, p-hacking), but each essentially involves probing the data in unplanned ways, finding and reporting an attractive result, without accurately conveying the course of analysis. I however tried various settings and for some ranges where the values were closer the coverage for the delta was good, the exponent version I never saw it vary. Data-dredging bias is a general category which includes a number of misuses of statistical inference (e.g. The delta method appears to overly optimistic at these settings. The delta method is giving me 0.9 coverage whereas the exponent version is returning the correct 0.95. I think I did it right, but just in case the code is attached for review. I did the following quick simulation study in R.
