Nixtla Time Series Cross-Validator

Acerca de

The Nixtla Cross-Validator skill provides a robust framework for assessing how well time series models generalize to unseen data by simulating future predictions. By automating expanding and sliding window techniques, it allows developers to integrate advanced validation into their workflows using TimeGPT and StatsForecast. This skill is indispensable for data scientists and engineers who need to benchmark multiple models, calculate precise error metrics like MAE and RMSE, and generate visual performance reports before deploying production-grade forecasting services.
