This method can be used to apply the lead and lag methods an arbitrary number of times to a dynSeries object. For instance, if ts is a dynSeries object, and if we define >> B = dynTimeIndex()-1; >> F = dynTimeIndex()+1; B and F can be used as lag and lead operators and the following syntax: >> us = ts(F^2); is equivalent to >> us = ts.lead(2) or >> us = ts.lead.lead
