**Methodology of Logistic Regression**

**Applies to:** StatTools 7.x

The user manual says, "The StatTools logistic regression procedure relies on optimization to find the regression equation. This optimization uses a complex nonlinear algorithm." Can you tell me anything more about the methodology?

The detailed code is proprietary, but we can tell you that it's based on Maximum Likelihood Estimators. StatTools uses an optimization process based on the conjugate gradient method to solve a system of nonlinear equations and find these estimators.
