new()Creates a new instance of this R6 class.
TaskRegrForecast$new(id, backend, target = "target", date_col = NULL)id(character(1))
Identifier for the new instance.
backend(DataBackend)
Either a DataBackend, or any object which is convertible to a DataBackend with as_data_backend().
E.g., a data.frame() will be converted to a DataBackendDataTable.
target(character(1))
Name of the target column.
date_col(character(1))
Name of the date column, only required if backend is a data.frame.
