Hi, I need to sort out where I went wrong. So, please us the data attached and run four separate regressions, each using the Recruiters rating as the dependent variable and GMAT, Accept Rate, Salary, and Enrollment, respectively, as a single independent variable. Interpret this equation.
Round your answers to four decimal places, if necessary. If your answer is negative number, enter "minus" sign.
Equation for GMAT:
Ŷ = _______ + _______ GMAT
Equation for Accept Rate:
Ŷ = _______ + _______ Accept Rate
Equation for Salary:
Ŷ = _______ + _______ Salary
Equation for Enrollment:
Ŷ = _______ + _______ Enrollment

- select bmw stock. you can assume the price of the stockarrow_forwardThis problem is based on the fundamental option pricing formula for the continuous-time model developed in class, namely the value at time 0 of an option with maturity T and payoff F is given by: We consider the two options below: Fo= -rT = e Eq[F]. 1 A. An option with which you must buy a share of stock at expiration T = 1 for strike price K = So. B. An option with which you must buy a share of stock at expiration T = 1 for strike price K given by T K = T St dt. (Note that both options can have negative payoffs.) We use the continuous-time Black- Scholes model to price these options. Assume that the interest rate on the money market is r. (a) Using the fundamental option pricing formula, find the price of option A. (Hint: use the martingale properties developed in the lectures for the stock price process in order to calculate the expectations.)
