Pastas has grown in to a full GitHub organisation with many useful tools to complement and improve the time series analysis experience. Important packages are:
PastaStore is a module that stores Pastas time series and models in a database. Storing time series and models in a database allows the user to manage time series and Pastas models on disk, which allows the user to pick up where they left off without having to reload everything. Additionally, PastaStore has a lot of tools to plot time series (spatially).
While Pastas can only do univariate time series analysis, Metran can perform multivariate timeseries analysis using a technique called dynamic factor modelling. It can be used to describe the variation among many variables in terms of a few underlying but unobserved variables called factors.
There are also related packages which are not part of the Pastas organisation but depend on Pastas or can be of interest for users for their time series analysis workflow:
