| Abstract | This paper introduces an alternative method for solving a problem of non-convergence in logistic regression. Themethod does not require any special software to be developed. It simply involves modifying the data by replacing the zerocount by 1 and doubling a corresponding non-zero count. The method is compared with that based on penalized likelihoodsuggested by Firth. Results show that the data modification method provides statistical significance of associations similar toFirth's method while using standard logistic regression output. |
