Вивчайте Predicting Customer Churn | Growth, Marketing, and Customer Insights

Predicting which customers are likely to leave your service—known as customer churn—is essential for startup growth. Churn directly impacts your revenue and can signal deeper issues with your product or customer experience. By identifying customers at risk of leaving, you can take targeted action to improve retention and reduce costly turnover.

from sklearn.linear_model import LogisticRegression

# Hardcoded customer data
data = {
    "monthly_usage": [120, 80, 200, 50, 300, 60, 90, 250],
    "num_complaints": [1, 3, 0, 5, 0, 4, 2, 1],
    "churned": [0, 1, 0, 1, 0, 1, 1, 0]
}

# Features and labels
X = df[["monthly_usage", "num_complaints"]]
y = df["churned"]

# Fit logistic regression

model.fit(X, y)

A logistic regression model is a popular choice for predicting binary outcomes like churn (yes/no). It estimates the probability that each customer will churn based on their features, such as monthly_usage and num_complaints. After training, you can interpret the model's predictions as the likelihood of a customer leaving, which helps you prioritize retention efforts.

# Predict churn for new customers
new_customers = pd.DataFrame({
    "monthly_usage": [70, 220],
    "num_complaints": [4, 0]
})
predictions = model.predict(new_customers)
probabilities = model.predict_proba(new_customers)[:, 1]

# Summarize results
for i, (pred, prob) in enumerate(zip(predictions, probabilities)):
    print(
        f"Customer {i+1}: Predicted churn = {bool(pred)}, Probability = {prob:.2f}"
    )
