Midterm: June 25th Solution
Final Examination Tuesday July 22 13:00-16:00 MNT207
Homework: Submit homework on Wednesdays. Late assignments will not be
Final Grade : If the grade on the final examination is less than 40% then
that is the final grade. If the grade on the final is 40% or more then the
final grade is calculated as:
Midterm Test: 25%
Final Examination: 50%
Total : 100%
NOTE: The midterm grade will be replaced by the grade on the final if the
later is higher. However, if you miss the midterm without a medical
certificate or an equivalent written justification then the midterm grade
will be zero and it won't be replaced.
First week: Reviewed joint densities and transformations of random
variables. Finished with a definition of a multivariate normal.
HW1 due May15 Solution
a) If X=(X_1,X_2,...X_n)' is a random vector. Define the covariance matrix S = E(X-EX)(X-EX)' Assuming the covariance is not singular show it is positive definite.
this means it has positive eigenvalues s_i and orthonormal
eigenvectors e_i. Show that the covariance matrix can be written
as s_1 e_1 e_1'+...s_n e_n e_n'. This is called the spectral
Show that S (1/2)= (s_1)(1/2) e_1 e_1'+...s_n(1/2) e_n e_n is the square root of the covariance matrix. Do the above operations for the matrix
