Hello everyone,
I have two questions regarding the configuration of the Numeric Outliers and GroupBy nodes that I’m hoping the community or the KNIME team could provide some insight on.
1. Numeric Outliers Node - LEGACY Estimation Method
The node description for Numeric Outliers states the following under the “Full data estimate using” option:
Since the value of the quartiles often lies between two observations, this option additionally allows to specify how the actual value is computed, which is encoded by the various estimation types (LEGACY, R_1, …, R_9). A detailed explanation of the different types can be found here.
The description explicitly lists LEGACY as the first method. However, in the node’s configuration dropdown, only the options from R_1 to R_9 are available.
Am I overlooking something, or is the LEGACY method mentioned in the description but not included in the node’s options?
2. GroupBy Node - Flow Variable for Pattern/Type Based Aggregation
My second query relates to the aggregationOperatorSettings flow variable in the GroupBy node.
This flow variable correctly becomes active in the “Flow Variables” tab as soon as a column is added under Manual Aggregation with a method that requires a parameter (e.g., Median, Quantile, Correlation).
However, the aggregationOperatorSettings does not seem to become active when using the Pattern Based Aggregation or Type Based Aggregation tabs. This prevents the programmatic configuration of aggregation parameters (like the quantile estimation method for all numeric columns) in these modes.
I am not sure if this is a missing feature or if I am missing a step to enable it. Being able to activate aggregationOperatorSettings for pattern and type-based aggregations is fundamental for creating fully configurable components.
I would greatly appreciate your feedback on these two points.
Thank you.
