However, typically in logistic regression we’re interested in the probability that the response variable = 1. The Solver automatically calculates the regression coefficient estimates:īy default, the regression coefficients can be used to find the probability that draft = 0.

Select a Solving Method: Choose GRG Nonlinear.

Make Unconstrained Variables Non-Negative: Uncheck this box.

By Changing Variable Cells: Choose the cell range B15:B18 that contains the regression coefficients.

Set Objective: Choose cell H14 that contains the sum of the log likelihoods.

Once the Solver is installed, go to the Analysis group on the Data tab and click Solver.

In the new window that pops up, check the box next to Solver Add-In, then click Go.

If you haven’t already install the Solver in Excel, use the following steps to do so: Step 8: Use the Solver to solve for the regression coefficients. Lastly, we will find the sum of the log likelihoods, which is the number we will attempt to maximize to solve for the regression coefficients. Step 7: Find the sum of the log likelihoods. Next, we will create values for log likelihood by using the following formula: Step 6: Create values for log likelihood. Next, we will create values for probability by using the following formula: Next, we will create values for e logit by using the following formula: Next, we will create the logit column by using the the following formula: Next, we will have to create a few new columns that we will use to optimize for these regression coefficients including the logit, e logit, probability, and log likelihood.

We will set the values for each of these to 0.001, but we will optimize for them later.

Since we have three explanatory variables in the model (pts, rebs, ast), we will create cells for three regression coefficients plus one for the intercept in the model. Step 2: Enter cells for regression coefficients. Use the following steps to perform logistic regression in Excel for a dataset that shows whether or not college basketball players got drafted into the NBA (draft: 0 = no, 1 = yes) based on their average points, rebounds, and assists in the previous season.

This tutorial explains how to perform logistic regression in Excel. Logistic regression is a method that we use to fit a regression model when the response variable is binary.
