KNIME Analytics Platform

Hi everybody, I wonder if it may be possible to add the Coefficient of Variation in the Groupby node.

Thank you

Hi Mau,

as far as I know is the Coefficient of Variation the ratio between the standard deviation to the mean. Both values are available as operations in the Groupby node and you could combine them to the Coefficient of Variation by using a subsequent Math Formular node.

I will also create a feature request for it.

Bye

Hi Tobias, please have a nice day… I wonder if this modification is still in your plans.

Thank you

Hello Mau,
sorry but I hadn’t created a ticket for this since you can compute it with two nodes. I have now created a ticket for this so we will look into it when we revisit the GroupBy node and the aggregation methods the next time.
Thanks
Tobias
