An open-source forecasting tool for time series data with multiple seasonality and linear or non-linear growth.
Prophet is an open-source forecasting tool developed by Facebook for producing high-quality forecasts from time series data. It uses an additive model to capture non-linear trends, multiple seasonalities (yearly, weekly, daily), and holiday effects, making it particularly effective for data with strong seasonal patterns. The tool is designed to be robust to missing data, trend shifts, and outliers, providing reliable predictions with minimal configuration.
Data scientists, analysts, and developers who need to generate accurate forecasts for business metrics, web traffic, sales, or other time series data with seasonal patterns, without deep expertise in time series modeling.
Prophet offers a straightforward, automated approach to forecasting that balances flexibility with ease of use, providing interpretable results and handling real-world data challenges like missing values and outliers more reliably than many traditional methods.
Tool for producing high quality forecasts for time series data that has multiple seasonality with linear or non-linear growth.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Handles missing data, trend shifts, and outliers effectively, as stated in the README, making it reliable for imperfect datasets common in business applications.
Automatically models yearly, weekly, and daily seasonalities plus holiday effects, with options for multiplicative seasonality, providing thorough seasonal capture without manual configuration.
Designed for analysts without deep time series expertise, with straightforward APIs in R and Python, and components like trend and seasonality that are easy to visualize and understand.
Includes cross-validation functions for model performance evaluation, as highlighted in the features, aiding in reliable forecast assessment and tuning.
The README explicitly warns that the CRAN version is fairly outdated, forcing users to install from GitHub for the latest bug fixes and holiday data, adding installation complexity.
Requires additional setup like Rtools or mingw-gcc, and the README notes it needs at least 4GB of memory for installation, which can be a hurdle in resource-constrained environments.
Based on an additive or multiplicative model, it may not capture advanced time series complexities like deep non-linear interactions or exogenous variables beyond holidays, limiting use for highly specialized forecasts.
