D Question 5 A time series variable such as a stock price tends to have an exponential trend. To straighten the trend, we can O take logs of the variable fit a regression model O maximize the R-squared O estimate the trend using OLS Question 6 The two solutions to correlated errors are Oi) get a larger sample or (ii) fix the model (1) keep the model and fix the standard errors or (ii) fix the model (i) keep the model and fix the standard errors or (ii) get a larger sample O keep the model and fix the standard errors or (ii) drop the outlier observations 1 pts MacBook Air 1 pts
