TimeSeriesMap

TimeSeriesMap[f, tseries] applies f to the values in tseries.

Examples

Apply a function to time series values:

ts = TimeSeries[{1, 2, 3, 4, 5}];
TimeSeriesMap[#^2 &, ts]

Take the logarithm of values:

TimeSeriesMap[Log, ts]

Apply a smoothing function:

TimeSeriesMap[MovingAverage[#, 3] &, ts]
