Root mean square calculation

frasau

Hi!
Can you tell me if there is an operator in RM to calculate the root mean square of a time series?

RMSE is typically a performance metric for evaluation of a regression type machine learning model where a numerical label has been predicted.  It can be found in the "Performance(Regression)" operator.  If your dataset is a label and an associated prediction for each row then it will be able to calculated using that operator.

hi, thanks for the reply! You're right, I explained myself wrong; I have a dataset with two attributes, time and a value as a function of time; I need to calculate the root mean square of this value and asked if there was an operator that did this calculation
