You are given the choice of two types of base classifiers (models) to use in a (bagged) committee: Classifier A: which is known to have an (error) variance of 40, but has been found to produce uncorrelated models under bagging Classifier B: which is known to have an (error) variance of 30, but has been found to produce models with a pairwise covariance of 0.3 under bagging Assuming Classifiers A and B have equal error bias and a committee of size 10, which Classifier would you choose and why?
Sol:
Personally, I would go for Classifier B : which is known to have an (error) variance of 30, but has been found to produce models with a pairwise covariance of 0.3 under bagging
Because having a variance of 0.3 is better than having uncorrelated models.

3. You will have just a single observation of X on which to base your choice between Ho: X has a Normal distribution with mean u = 5 and standard deviation o = 2 а VS. H1:X has a Binomial distribution with n =25 and p = 0.20. Consider the rejection rule "Reject Ho if X is an integer" Find a P(Type I Error) and B = P(Type II Error). Justify your answer.

SOME DRAWBACKS OF BLACK-SCHOLES To provide one motivation for the development of ARCH models (next handout), we briefly discuss here some difficulties associated with the Black Scholes formula, which is widely used to calculate the price of an option. For example, consider a European call option for a stock. This is the right to buy a specific number of shares of a specific stock on a specific date in the future, at a specific price (the exercise price, also called...
