Hi RapidMiner Team,

I want to calculate the difference between two consecutive values in an attribute, but I do not which operator I can use.

For example: my dataset idspeed115218320430 I want to calculate the difference between two consecutive speed and generate a new attributes names "difference". idspeeddifference115n.a.2183320243010 How can I do this?

Hello

The "Lag Series" operator is the one to use - this is part of the Series extension so you need to install this additionally.
