ANALYTICS:Chomp=cutoffTimestampInSeconds
(:stripNaNs)
where:
- cutoffTimestampInSeconds is a time stamp, in seconds.
|
| Filter
Alters the data source by adding one or more columns and/or
modifying the existing values.
|
| FilterFactory
Used to instantiate a

ANALYTICS:HoltWinters=outputPrefix
:inputColumn
(:numPeriodsToForecast)
(:periodInSeconds)
(:confidenceLevel)
where:
- inputColumn is the name of the column whose values we want to forecast
- numPeriodsToForecast is the number of periods we want to forecast
- periodInSeconds is the length of a period (or season) in seconds, if
this value is < 1, then we assume that every sample is a period.

ANALYTICS:TrendLine=outputColumn
:inputColumn
(:secondsAhead)
(:polynomialOrder)
where:
- inputColumn is the name of the column whose values we want to trend
- secondsAhead is the number seconds ahead the of the column for
which we want to include the trend line
