What you'll learn:
- Master Binary Logistic Regression, a crucial classification technique in data science, machine learning, and statistics.
- Learn to predict binary outcomes (yes/no, true/false, sick/healthy) based on continuous independent variables.
- Perform and interpret Binary Logistic Regression analysis using Minitab with ease and accuracy.
- Analyze and interpret the Confusion Matrix to evaluate the performance of your model.
- Learn to use the Receiver Operating Characteristic (ROC) Curve for assessing model accuracy.
- Apply your knowledge through project work, such as evaluating the effectiveness of an ad campaign for a new cereal.
- Build a strong foundation in logistic regression to boost your career in data science, machine learning, and statistical analysis.
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.
