Group Summary of Time

If a time column is specified, the Time Series Forecast report contains a section of summaries of the individual time series. The summaries contain the following information for each time series:

<Grouping Column Name>

(Available only if a Grouping variable is specified.) The level of the grouping variable that defines the individual series when data is provided in the stacked format.

N Rows

The number of observations in the series.

Missing Value

Indicates whether any of the time values are missing values.

Unique Timestamps

Indicates whether the time stamps are unique.

Start

The starting time stamp.

End

The ending time stamp.

Missing Record

Indicates whether there are observations missing from the data table, based on the starting and ending time stamps and the data resolution/pattern.

Tip: The Group Summary of Time table is linked to the Select Series list. When you select a series in the Group Summary of Time table, the corresponding entries are also selected in the Select Series list.Group Summary of Y

The Time Series Forecast report includes a summary table for each Y variable. The summaries contain the following information for each time series:

Variable

(Available only if there are multiple Y columns and at least one grouping column.) The column name of the time series variables.

Time Series

(Available only if there are multiple series.) The name of the individual time series. When the data are provided in the stacked format, this is the level of the grouping variable. When the data are provided in the wide format, with multiple columns, this is the column name of the individual series.

Note: When the data are provided in the stacked format, the column heading in the table is the name of the Grouping column.

Min

The minimum value of Y for the individual series.

Max

The maximum value of Y for the individual series.

Length

The duration of the series. This is determined based on the starting and ending time stamps and the result of the Analysis of Time Pattern.

N Obs

The number of observations. If there are no missing records, this number is the same as the Length.

N Missing

The number of missing Y values.

All Positive

Indicates whether all of the Y values are positive.

Comment

Indicates if there is a problem with the series, such as non-unique time stamps.

Tip: The Group Summary of Y table is linked to the Selected Series list. When you select a series in the Group Summary of Y table, the corresponding entries are also selected in the Select Series list.
