Prophet is a forecasting tool designed for analyzing time-series data. It is a procedure for forecasting time series data based on an additive model where non-linear trends are fit with yearly, weekly, and daily seasonality, plus holiday effects. It was developed by the research team at Facebook and is available as an open-source software.

The History of the Origin of Prophet and the First Mention of It

Prophet was initially developed and released by Facebook’s Core Data Science team in 2017. The primary aim was to provide a tool that could be easily utilized by analysts and developers alike without the need for extensive statistical knowledge. Its implementation in Python and R made it accessible to a broad audience, and it quickly gained popularity in various industries for its ability to handle the challenges of forecasting at scale.

Detailed Information about Prophet: Expanding the Topic

Prophet has become a key tool in time series forecasting, thanks to its flexibility and robustness. The following details expand upon the components of Prophet:


  1. Trend Model: Identifies underlying trends in the data.
  2. Seasonality Model: Captures periodic fluctuations in the data, such as daily, weekly, and yearly patterns.
  3. Holiday Effects: Accounts for holidays or special events that might influence the data.
  4. Error Term: Considers the random variations that cannot be explained by the model.


Prophet uses an additive model that combines these components, and it incorporates uncertainty intervals to capture uncertainty in the forecasts.

The Internal Structure of the Prophet: How the Prophet Works

The working of Prophet is defined by its additive model that combines different components:

  • Trend: Linear or logistic growth trend in time-series.
  • Seasonality: Weekly and yearly seasonality with Fourier series.
  • Holidays: User-provided list of dates to model effects of holidays or special events.

The model is fit using a variation of the Generalized Additive Model (GAM) framework and uses Stan, a probabilistic programming language for estimation.

Analysis of the Key Features of Prophet

  1. Robust to Missing Data: Handles missing data points without needing imputation.
  2. Automatic Detection of Seasonality: Automatically detects seasonal patterns.
  3. Inclusion of Holidays: Allows for special modeling around holidays and events.
  4. Flexibility: Offers flexibility in modeling trends and seasonal effects.
  5. Scalability: Capable of handling large datasets.

Types of Prophet: Table and Lists

There is mainly one type of Prophet model, but it can be configured for different types of growth:

Growth Type Description
Linear Assumes linear growth without any bounds.
Logistic Assumes growth that slows down and hits a saturation point.
