Chapter 8.1, Problem 30E
Student Residences According to the Higher Education Research Institute, 80% of students at baccalaureate-granting colleges who entered college in 2015 lived in College residence halls, 15% lived with Family, and 5% lived in Other types of housing. Suppose that each year, these students changed their residences as described by the following matrix. (Source: The American Freshman: National Norms Fall 2015.)
a. What percentage of the students who lived with family as freshmen lived in college residence halls as sophomores?
b Explain the meaning of the .8 appearing in the center of the matrix.
c. Draw the transition diagram for this Markov process.
d. What percentage of the students lived in college residence halls as sophomores? As juniors?

Students have asked these similar questions
The OU process studied in the previous problem is a common model for interest rates.
Another common model is the CIR model, which solves the SDE:
dX₁ = (a = X₁) dt + σ √X+dWt,
-
under the condition Xoxo. We cannot solve this SDE explicitly.
=
(a) Use the Brownian trajectory simulated in part (a) of Problem 1, and the Euler
scheme to simulate a trajectory of the CIR process. On a graph, represent both the
trajectory of the OU process and the trajectory of the CIR process for the same
Brownian path.
(b) Repeat the simulation of the CIR process above M times (M large), for a large
value of T, and use the result to estimate the long-term expectation and variance
of the CIR process. How do they compare to the ones of the OU process?
Numerical application: T = 10, N = 500, a = 0.04, x0 = 0.05, σ = 0.01, M = 1000.
1
(c) If you use larger values than above for the parameters, such as the ones in Problem
1, you may encounter errors when implementing the Euler scheme for CIR. Explain
why.
