# Churn Analysis
Churn Analysis application predicts the customer churn score that indicates the probability of customer getting churned. Churn analysis is modeled as a typical classification problem. Training data is generated from the historical sales and payment data, a target label is assigned to each customer indicating whether he has churned or not. This training data is used to train a model which will be used to predict the churn score of new customers.
## How to build my first Churn Analysis app?
### Data Preparation
**Sample dataset:**
To get you started immediately, we have provided a sample training data set of telecommunication business, which contains 19 different features and a target label named **Churn**. The value of target label is either *True* or *False*, defining whether the customer has churned or not.

### Build App
1. Go to the app store, build a churn analysis app by searching for *Churn Analysis*
2. You will be redirected to the app settings page where you can configure and run the app
3. Under **Quick Settings**,
3.1. Select an existing dataset or upload a new dataset and click **Save**
3.2. Select the target field, the field that indicates whether customer is churned or not, and click **Save**
4. Now click on **Run Now** to start the app. The app may run for 5 to 20 minutes (dependending on the size of input data) and then the trained model will be saved.
5. Use this model to get the churn prediction
5.1. Click on **Build App** on the model to build the inference app using that model
5.2. Provide the input in the given fields and click on **Get Results**. The predicted churn class and scores will be displayed on the right side of the screen.
6. [Optional] To use this model to predict more than one examples, [Visit here] [TODO]
### Output
The output of the infer app will the predicted class (churn or non churn) and probability score of prediction.
