The Abdi-Basid Courses Institute was inaugurated on March 13, 2017, in Dakar, Senegal. It is a fully virtual platform aiming to unveil the engine of science and make it accessible to all. We offer online courses, live sessions, and multimedia content across fields. Our mission is to bridge science and society through inclusive, flexible, and engaging learning for students, professionals, educators, and curious minds worldwide. https://sites.google.com/view/theabdibasidcoursesinstitut/accueil
This data analysis project explores customer behavior on an e-commerce platform using a dataset containing key metrics such as session duration, product detail views, app transactions, add-to-cart rate per session, discount rate per visited products, credit card info saving, average order value (“avg order value”), and a high-value customer indicator (“high_value_customer”). The code is structured in several steps:
Data Preparation: Loading from the clipboard, cleaning (replacing commas with periods for decimals), numeric conversion, and encoding of categorical variables (e.g., yes/no via LabelEncoder).
Regression Modeling: Use of an XGBoost model to predict average order value, with evaluation via RMSE and R² on a test set (30% of the data). Visualizations include a scatter plot of predictions vs. actual values, a correlation matrix, a boxplot of average basket by card saving, and a histogram of prediction errors.
Classification Modeling: Logistic regression with L2 regularization to identify high-value customers, based on selected features (session duration, product views, etc.). Evaluation via ROC-AUC score and ROC curve.
