applies f to the values in tseries.


  • TimeSeriesMap is used to apply functions to the values in a time series.
  • TimeSeriesMap can be used for regularly and irregularly spaced time series.
  • The input tseries can be a list of values {x1,x2,}, a list of time-value pairs {{t1,x1},{t2,x2},}, a TimeSeries, an EventSeries, or TemporalData.
  • TimeSeriesMap threads pathwise for tseries with multiple paths.
