There is a new chart in RapidMiner Go showing actuals vs. predictions and a confidence interval. How is CI & margin of error calculated? Is it based on standard error of all the coefficients at 95% confidence level? Just looking for the underlying math. thanks!

Hi Michael,
RapidMiner Go draws the 95% confidence interval based on the absolute error variance returned by the Performance(Regression) operator in Studio Core. The operator is documented here: https://docs.rapidminer.com/latest/studio/operators/validation/performance/predictive/performance_regression.html
If you want to know exactly how that variance is calculated we need to loop in a data scientist like @mschmitz
