Information about the Final Exam


You can come by my office to pick up your homework on Thursday December 6 11am-1pm or Friday December 7 10am-3pm.


Syllabus

The syllabus can be found here.



Statistical Education Center (SEC)

The SEC offers help sessions from 4pm to 9pm Sunday through Thursday in Old Chemistry 211A. A team of teaching assistants are available for students to ask questions on material from undergraduate and graduate courses taught by the Statistics department.

Our TA's hold their office hours in that room. In addition, most Graduate student TAs would be able to help you with the material in STA 611.

The Schedule of the SEC can be found here

Mathematical Background


Familiarity to the following concepts is essential for your success in this course:
Function, limit, continuity, differentiation (e.g. product rule, quotient rule and chain rule), integration, integration techniques such as integration by parts and by substitution, function of two variables, double integrals, ifinite series, maxima and minima of functions.

Take this quiz by yourself, preferably before classes start and no later than by our second class (Thursday August 30) to help you determine whether you have the necessary math- ematical background. It should take no more than an hour. Do not look at the solutions beforehand!
