Use the Excel Solver To Calculate the Predictive Equation
To Solve for the Predictive Equation P(X),You Need To Solve for L (the Logit)
You Will Use the Excel Solver to Solve for “Solver Decision Variables” (A, B, and Constant) Which Cause the Predictive
Equation P(X) To Be As Accurate As Possible
As Before Running the Solver, Create the Following Data Columns on a Spread Sheet
The Fundamental Basis for Logistic Regression Is Solving For The Above Equation
