Accurate forecasts for time series with seasonality.
4 months ago
As a business analyst, Prophet is my go-to for quick forecasting. It's incredibly easy to use—you don't need a deep statistical background. It handles seasonality and holidays automatically, and the output charts showing the trend, weekly, and yearly components are perfect for explaining results to stakeholders. It provides a solid baseline forecast in minutes.

Prophet is great for a first pass, but it struggles with highly irregular time series or when external regressors have a complex relationship with the target. I found I had to move to more traditional models like ARIMA or deep learning models (LSTMs) for higher accuracy on our core business metrics. It's a great tool in the toolbox, but not the only one.

The best part of Prophet is its ability to automatically detect changepoints where the trend suddenly changes. This helped us identify the exact month a competitor's marketing campaign started impacting our sales. The ability to manually add changepoints and holidays is also incredibly powerful. It's a very practical, business-focused forecasting tool.
