TimeSeriesInsert

TimeSeriesInsert[tseries,{t,v}]

inserts a value v at time t in the time series tseries.

TimeSeriesInsert[tseries1,tseries2]

inserts the time-value pairs from tseries2 into tseries1.

Details

  • TimeSeriesInsert is often used to add a value to a time series, to concatenate two time series, or to replace erroneous or missing values.
  • The time series tseries can be a list of numeric values {x1,x2,…}, a list of time-value pairs {{t1,x1},{t2,x2},…}, a TimeSeries, an EventSeries, or TemporalData.
  • The time t can be given as numbers or dates.
  • If a value is already present at time t it will be replaced by v.
