| This app takes seven inputs about employees' satisfaction with different aspects of their work (such as Passionate at Work, ...) and predicts whether the employee intends to stay with the employer or leave. There are two outputs from the app: 1- the predicted probability of stay or leave, 2- Shapley's force-plot which visualizes the extent to which each factor impacts the stay/ leave prediction. | |
