`transform` vs. `rolling` vs. `flagGeneric
All of the above function full fill a similar purpose, transforming data using a custom function. AFAICT the differ in the folling way:
-
transform
: applies a function on non-overlapping chunks -
rolling
: basic rolling window application -
flagGeneric
: any computation, allows rolling operations on the input series as well
@luenensc: I wonder, if we could somehow unify this methods?
