Regression analysis can be used to test whether the market efficiently uses information in valuing stocks. Let return be the total return (measured in %) from holding a firm's stock over the four-year period from the end of 1990 to the end 1994. The efficient markets hypothesis (EMH) says that these returns should not be systematically related to information known in 1990. If firm characteristics known at the beginning of the period help to predict stock returns, then we could use this information in choosing stocks. For 1990, let dkr be a firm's debt-to-capital ratio, let eps denote the earnings per share, let netinc denote the net income, and let salary denote total compensation for the CEO. Using the data in Computer_Exercse_10.xlsx, please answer the following questions. Assume throughout that assumptions MLR.1-MLR.6 are satisfied.
