- DSL: Support global time series in
graph_signal(…). If a
graph_signal(…) only has global data, it now always returns that data,
even if it is evaluated for a different entity. This allows for example adding
together graph signals with data for entities with global graph signals.
- DSL: Allow the bracket operator, which does column selection, to work on all types
of signals, also those which return time series for multiple entities.
Assuming a signal returns time series for multiple regions, where one of them
is named
Europe, you can now do: graph_signal(…)['Europe'] to select
that time series.
- DSL: Add
alpha parameter to control width of the confidence band for
unobserved components forecasts, and include the confidence band for the
in-sample period.
- DSL: Fix bug in
series_function(..) which prevented it from being used on
results from the portfolio allocation signal.
