R: Classify a new X as coming from population 2 ifWe want to estimate the error rates for this classifier. The usual linear rule for known parameters would classify X in group 2 if and have an error rate of
where
Use the result in the first 3 parts of this question but with 1 smaller get a formula for the expected value of this estimate plus terms like .
