One thing I’d like to see added for predictive model evaluation is MAPE. For example, the RSquare and Root Averaged Squared Error (RASE) is shown for the training and validation data (this is from the regression report). It would be helpful, since we typically use MAPE on holdout to access accuracy of predictive models, to have it available in this report. As it stands, we have to calculate by creating a new column.
MAPE = Mean Absolute Percentage Error = In Greg's example, for each of the points in the test or validation set calcuale abs(actual - predicted)/ actual, then calculate the mean.
Archived as a duplicate of MAPE in model reports.
This is the same as MAPE in model reports.
Archiving this one.
