disaggregate by setting a weight for each output point |
Input
- InputVariable
configuration
- weights for each point
Output
- OutputVariable
Description
This transformation performs a disaggregation from times series to another series in which each output points is multiplied bu a specified weight. There MUST be a weight for each output point or the disaggregation will fail. E.g. when converting 15 minute values to 5 minute values three weight elements must be specified.
Each output time series value within a given data time interval of the input time series is equal to the input time series value multiplied by the weight specified for the output time.
The table below shows a simple example of the procedure.
Time | Input | Output | Weight |
|---|---|---|---|
12:00 | x | 0.5 | 0.5 |
00:00 | 1 | 1 | 1 |
12:00 | x | 2 | 0.5 |
00:00 | 2 | 2 | 1.0 |
In this case two eigth elements (0.5 and 1.0) have been specified. Note that the order in which the elements appear determines to which point they are applied.
