What you'll learn

Mastering Binary Logistic Regression

Perform and interpret the results of Logistic Regression Analysis using Minitab

Requirements

You should have a good understanding of the Linear and Multiple Regression Analysis

Else take my Mastering Multiple Regression with Minitab: A Deep Dive course before starting this course.

You can download 30 days trial version of Minitab for practice from their website

Description

In this course, I will teach you one of the most commonly used classification techniques in data science, machine learning and statistics and that is: Binary Logistic Regression.

A binomial logistic regression is used to predict the binary output (yes/no, true/false, sick/healthy) based on one or more continuous independent variables. It is often referred to as logistic regression. However, in Minitab, it is called binary logistic regression.

I will use Minitab 19 to perform the analysis. The focus of my teaching will be on explaining the theoretical concepts and on analyzing and interpreting the results of the analysis.

Performing Binary Logistic Regression in Minitab is easy. It is just a few selections and clicks and you are done with it. However, the difficult part is understanding and interpreting the results.

The following concepts are covered in this course:

The purpose of Binary Logistic Regression

The concept of Odds and ln(Odds)

Logistic Regression Equation

Odds Ratio

Confusion Matrix

Receiver Operating Characteristic (ROC) Curve

R-Squared in context of Logistic Regression

Hosmer-Lemeshow Goodness of Fit Test

Project work to practice all the above concepts

In the project work, marketers at a cereal company investigate the effectiveness of an ad campaign for a new cereal. Three factors considered in this project are the income, whether the person has seen the advertisement and whether the person has kids in the house.

Here we performed binary logistic regression to determine whether people who saw the ad are more likely to buy the cereal.

After completing this course, you will be easily able to perform the logistic regression, select the model.

Who this course is for:

Six Sigma or Data Analysis professionals who want to take their understanding of Regression Analysis to the next level.

Anyone who wants to get a more in-depth insight into interpreting the Logistic Regression results
