FORECAST_ETS_CONFINT
function FORECAST_ETS_CONFINT(
arg1: number = null,
arg2: ApiRange | number[] = null,
arg3: ApiRange = null,
arg4: number = null,
arg5: number = null,
arg6: number = null,
arg7: Aggregation = null,
): numberDescription
Returns a confidence interval for the forecast value at the specified target date.
Parameters
- arg1
numberdefault: null A date for which a new value will be predicted. Must be after the last date in the timeline.
A range or an array of numeric data that determines the historical values for which a new point will be predicted.
A range of date/time values that correspond to the historical values. The timeline range must be of the same size as the second argument. Date/time values must have a constant step between them and can't be zero.
- arg4
numberdefault: null A number between 0 and 1 that shows the confidence level for the calculated confidence interval. The default value is .95.
- arg5
numberdefault: null An optional numeric value that specifies the length of the seasonal pattern. The default value of 1 indicates seasonality is detected automatically. The 0 value means no seasonality.
- arg6
numberdefault: null An optional numeric value to handle missing values. The default value of 1 replaces missing values by interpolation, and 0 replaces them with zeros.
An optional numeric value to aggregate multiple values with the same time stamp.
