## 📌 Summary  

Development of a predictive model for the **"display"** variable using Machine Learning techniques by transforming all continuous variables into categorical for modeling.

### 1️⃣ Data Presentation  

📌 **Descriptive analysis** of qualitative and quantitative variables, and their transformation for analysis.

### 2️⃣ Multiple Component Analysis (MCA)  

📉 Use of **MCA** to reduce data dimensionality, identify principal components, and interpret results.

### 3️⃣ Modeling  

- **Decision Tree**: Classification with specific parameters and a **confusion matrix** to assess performance.  

- **Random Forest**: Application of **random forest**, parameter tuning, and classification results.  

- **Logistic Regression**: Prediction using logistic regression, including **error rates** and accuracy metrics.

### 4️⃣ Model Comparison  

📊 Comparative analysis of three machine learning models: **Decision Tree, Random Forest, and Logistic Regression**.

### 5️⃣ Model Performance (Best Model Analysis)  

📏 Evaluation of model performance based on **precision** and **sensitivity**.

🚀 **Let's make data-driven decisions!**
