Extract Aggregates operator : Error in functions calculation ?
Hi RM Staff,
First I hope everyone is doing well.
Secondly, I think there is an error of calculation in the Extract Aggregates operator (Time-series module) for the :
- median
- first quartile
- third quartile
It seems that these 3 functions are assimiled to the "minimum" function...
Here the results for the "Temperature" attribute of the "Golf" dataset :
These curious results allowed me to test the new function "percentile" of the Aggregate operator. This operator give (from my point of view)
the good following results :
The process (use RM 9.1 (beta) to run this process) :

Lionel
