1 Using The Function Mp Sample Tw Compute The Average Uniqueness Of Each Label What 2664290

1. Using the function mp Sample TW, compute the average uniqueness of each label. What is the first-order serial correlation, AR(1), of this time series? Is it statistically significant? Why?

2. Fit a random forest to a financial dataset where

(a) What is the mean out-of-bag accuracy?

(b) What is the mean accuracy of k-fold cross-validation (without shuffling) on the same dataset?

(c) Why is out-of-bag accuracy so much higher than cross-validation accuracy? Which one is more correct / less biased? What is the source of this bias?
