public class TimeSeriesTranslateFilter
extends AbstractTimeSeriesFilter
An instance filter that assumes instances form time-series data and replaces attribute values in the current instance with the equivalent attribute attribute values of some previous (or future) instance. For instances where the desired value is unknown either the instance may be dropped, or missing values used.

Valid filter-specific options are:

-R index1,index2-index4,...
Specify list of columns to calculate new values for. First and last are valid indexes. (default none)

-V
Invert matching sense (i.e. calculate for all non-specified columns)

-I num
The number of instances forward to translate values between. A negative number indicates taking values from a past instance. (default -1)

-M
For instances at the beginning or end of the dataset where the translated values are not known, use missing values (default is to remove those instances).
