Limit theorems. Sampling distributions. Parametric estimation. Concepts of
sufficiency and efficiency. Neyman-Pearson paradigm, likelihood ratio tests.
Parametric and non-parametric methods for two- sample comparisons. Notions
of experimental design, categorical data analysis, the general linear model,
decision theory and Bayesian inference.

Prerequisites: MAT2125, MAT2141, MAT2375 (MAT3172 and or MAT4371 would be helpful)

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:
Homework: 25%
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.

Show 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 decomposition.

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
