LauraAlbrecht608310: I have never used this feature. I looked in the documentation and found very little helpful information. The documentation page on
Adaptive evaluation gives scant detail on how it works. The page on
Variables & Prompts describes the different ways in which an object variable may be used for adaptive ERT:
You can define the object variables as external factors for the
adaptive ERT calculation. Select the relevant data type for the
variable's value from the following items:
- Nominal(= character string)
- Numeric
- Timestamp
- Date
- Time
- No ERT Usage(= do not use object variable for adaptive ERT)
This variable will then be taken into account in the adaptive ERT calculation process.
I found no detailed description of what each of these options actually means, what form it should take, or how it affects ERT calculation. The
documentation contains no examples.
My
guess is that it works something like this: The first five items in the list above are
weighting factors, used in calculating the
estimated run time. They are normally picked up from the statistics of the run of the task. If one wishes to
override the values of any of these weighting factors, one can do so by specifying that a particular
object variable’s value should be used for this a particular weighting factor, instead of the actual data from the run of the task.
