Build ARCH and GARCH models on the provided dataset. Create an MLOps pipeline using the Amazon Web Services (AWS) platform to deploy the time series ARCH model in a production environment.

Autoregressive conditional heteroskedasticity is a time-series statistical model used to analyze volatility in high frequency data.

ARCH and GARCH models directly address the dependency of conditional second moments, and have proved particularly valuable in modelling processes where a relatively large degree of fluctuation is ...
