StatsForecast is a production-grade Python library for large-scale univariate time series forecasting. It provides a unified API (fit/predict/forecast/cross_validation) over 40+ statistical models including AutoARIMA, AutoETS, AutoCES, AutoTheta, MSTL, TBATS, GARCH, and intermittent-demand methods (Croston, ADIDA, IMAPA). The core algorithms are implemented in C++ via pybind11 for performance, with Python wrappers handling model selection, prediction intervals, and conformal prediction. The library supports distributed execution on Spark, Dask, and Ray through a Fugue-based backend, and integrates with pandas, Polars, and MLFlow. While primarily an application library, the repository also contains extensive benchmarking experiments against R packages, Prophet, and NeuralProphet, as well as tutorials and competition notebooks, giving it a hybrid character. The codebase is well-structured with a clear separation of concerns (core API, model implementations, distributed backends, utilities) and includes a comprehensive test suite validated against R reference values.
This is an R package (`parameters`) from the easystats ecosystem that provides a unified interface for extracting, formatting, and comparing parameters from a vast array of statistical models (lm, glmmTMB, brms, lme4, lavaan, fixest, etc.). The package functions as a model-parameter reporting engine: it takes a fitted model object and returns a tidy data frame with coefficients, standard errors, confidence intervals, p-values, and effect sizes, supporting various inference methods (Wald, profile, bootstrap, Kenward-Roger, Satterthwaite). Beyond basic extraction, it offers standardization, bootstrapping, equivalence testing, p-value functions, dominance analysis, and data reduction (PCA, EFA, clustering). The architecture relies heavily on S3 generic dispatch (e.g., `model_parameters.lm`, `model_parameters.glmmTMB`) and integrates with the easystats stack (`insight` for model introspection, `bayestestR` for Bayesian indices, `datawizard` for data manipulation). Output can be formatted as plain text, markdown, or HTML, making it suitable for both interactive use and automated reporting. The package is actively maintained with extensive test coverage and continuous integration.
