Logistic Regression Practical Case Study

Breast Cancer detection using Logistic Regression

What you’ll learn

  • How to build a Logistic Regression model for a Real-World Case Study
  • Work on Google Colab


  • Basic theory of Logistic Regression


Did you know that approximately 70% of data science problems involve classification and logistic regression is a common solution for binary problems?

Logistic regression has many applications in data science, but in the world of healthcare, it can really drive life-changing action.

In this SuperDataScience case study course, learn how to detect breast cancer by applying a logistic regression model on a real-world dataset and predict whether a tumor is benign (not breast cancer) or malignant (breast cancer) based off its characteristics.

By the end of the course, you will be able to build a logistic regression model to identify correlations between the following 9 independent variables and the class of the tumor (benign or malignant).

  • Clump thickness
  • Uniformity of cell size
  • Uniformity of cell shape
  • Marginal adhesion
  • Single epithelial cell
  • Bare Nuclei
  • Bland chromatin
  • Normal nucleoli
  • Mitoses

Logistic regression can identify important predictors of breast cancer using odds ratios and generate confidence intervals that provide additional information for decision-making. Model performance depends on the ability of the radiologists to accurately identify findings on mammograms.

More about logistic regression:

Logistic regression is a method of statistical analysis used to predict a data value based on prior observations of a dataset. A logistic regression model predicts the value of a dependent variable by analyzing the relationship between one or more existing independent variables.

In data science, logistic regression is a Machine Learning algorithm used for classification problems and predictive analysis.

More real-world applications of logistical regression include:

  • Bankruptcy predictions
  • Credit scoring
  • Consumer behavior
  • Customer retention
  • Spam detection

Who this course is for:

  • Anyone interested in Machine Learning, AI or Data Science
  • Anyone who wants to learn how to make accurate predictions
