Suppose a company has hourly readings from 800 sensors for a whole year that are used to monitor theworkings of a large system of industrial equipment. Given some labeled anomalies, an engineer wants to build a classifier to predict anomalies from future readings of these sensors. She trains a machinelearning model and uses 10-fold cross-validation to tune hyper-parameters (using vanilla methods from scikit-learn, for example). When new data comes in, however, the accuracy of the classifier is poor. She is confused as the cross-validation error was quite good. What might explain these results?

Any point on a country's production possibilities frontier represents a combination of two goods that an economy:

Which of the following statements is correct? stockholders should generally be happier than bondholders to have managers invest in risky projects with high potential returns as opposed to safe projects with lower expected returns. potential conflicts between stockholders and bondholders are increased if a firm's bonds are convertible into its common stock. takeovers are most likely to be attempted if the target firm’s stock price is above its intrinsic value. one advantage of operating a business as a corporation is that stockholders can deduct their pro rata share of the taxes the firm pays, thereby eliminating the double taxation investors would face in a partnership.
