You need to quantify the uncertainty in a regression model forecast of applicants’ future profitability. Assume that both the forecast profits and the errors have a Gaussian distribution. You will calculate the standard deviation of model error on standardized data, the standard deviation in dollars of the model error, and the 90% confidence interval for profitability estimates.
Question: What is the standard deviation of your model error on the standardized Training Set output?
