for BMA/MA/ST 773-001 Smith Section FALL 2002


HW # 1
1. write a paragraph or abstract of "Single Point, Single Dose
article as per example. Also find an article on transformations
or correlation functions and write a similar abstract
. HW # 2
passed out problem on convergence in distribution and transformations

HW # 3 due Thurs Sept 12
for the cow's milk example, take Xo =10, r=0.3, S=1
using forward difference method over [0,10] time simulate dX/dt = -r X and compare to exact solution a) using dt = 0.2 b) repeat using dt = 1.0 c) repeat using dt =2.0 d) using dt = 0.2 and letting r be a UNIFORM random variable over [0.2, 0.4] simulate 100 sample paths of the first crossing time to reach S=1. Compare your simulation result to the theoretical crossing time distribution using a chi-squared goodness of fit test

HW # 5 
due 
1) Using Box Mueller transformation, simulate 1001 normal(mean=2, variance=25) variates make a scatter plot of X(n) vs X(n-1), does it look independent? compute the serial correlation coef. compute the marginal of X(n) and of X(n-1), overlay the theoretical distribution on top of it. 2) repeat question 1) with u1 and u2 interchanged in the second equation. comment on the shape of the scaterplot. are the marginals still normal looking?
