TimeSeriesQ

TimeSeriesQ[expr]

gives True if expr is a valid TimeSeries object, and False otherwise.

Details

  • TimeSeriesQ tests whether an input is a valid TimeSeries object.
  • A valid time series has head TimeSeries and stores same-length lists of times and values.

Basic Examples  (2)

Test whether an object is a valid time series:

Wolfram Language code: TimeSeries[{70.2, 78.5, 75.1}, {Today}]
Wolfram Language code: TimeSeriesQ[%]

Test whether FromTabular returned a valid time series:

Wolfram Language code: FromTabular[Tabular[Association["RawSchema" -> Association["ColumnProperties" -> Association["Time" -> Association["ElementType" -> "Integer64"], "Value" -> Association["ElementType" -> "Integer64"]], "KeyColumns" -> None, "Backend" -> "WolframKernel"], "Options" -> {}, "BackendData" -> Association["ColumnData" -> DataStructure["ColumnTable", {{TabularColumn[Association["Data" -> {{1, 2, 3}, {}, None}, "ElementType" -> "Integer64"]], TabularColumn[Association["Data" -> {{1, 2, 3}, {}, None}, "ElementType" -> "Integer64"]]}}]]]], "TimeSeries"]
Wolfram Language code: TimeSeriesQ[%]

Properties & Relations  (2)

Empty TimeSeries objects are valid:

Wolfram Language code: TimeSeries[{}]
Wolfram Language code: TimeSeriesQ[%]

Valid EventSeries objects are not valid time series:

Wolfram Language code: es = EventSeries[{"a", "b", "c"}, {{1.2, 1.5, 1.9}}]
Wolfram Language code: EventSeriesQ[es]
Wolfram Language code: TimeSeriesQ[es]
