Chapter 14, Problem 1P
Define each of the following terms:
a. Factor
b. Level
c. Two-factor study
Expert Solution & Answer
To determine
Definitions of each of the following terms:
- Factor
- Level
- 2 factor study
Explanation of Solution
- Factor: The factor is an independent variable and is an explanatory variable that is manipulated by the experimenter. It designates the group being compared.
- Each factor has 2 more levels. Combination of different levels of factors make treatments.
- 2 factorstudies have 2 explanatory variables which the researcher is trying to study. Each factor may have different levels 2 or 3 each. That leads to 2 way Analysis of Variance. Each main effect,interaction between 2 factors,residual error and total variance can be studied in ANOVA and F tests are conducted to find its significance.

- This 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.)
