Fill Data Gaps


Synopsis

This operator fills gaps in the data based on the ID attribute of the data set.


Description

This operator fills gaps in the data based on the ID attribute of the data set. The ID attribute must either have the value type "integer" or one of the data value types.

The operator performs the following steps:

    * The data is sorted according to the ID attribute
    • All occurring distances between consecutive ID values are calculated
    • The greatest common divisor (GCD) of all distances is calculated
    • All rows which would have an ID value which is a multiple of the GCD but are missing are added to the data set

Please note that all values of attributes beside the ID attribute will have a missing value which often must be replaced as a next step.
