13.  Introduction to Survival Analysis
          Breast Cancer Data     |     Treadmill Data
14.  Poisson Regression
          Selvin's data:      Table 12.4     |     Table 12.11     |     Table 12.13     |     Table 12.24
15.  Power and Sample Size     |     Cohen Paper     |     A few references

At the request of a former student, I have combined all these notes into one (large!) file.
I have not added a table of contents or index, i.e. there is nothing new.
If you want that large file click here.  This does not include separate data or supplements.

This is really incomplete, but I often get asked for a flowchart to procedures

We will be spending the first week or so of the course getting familiar with Stata and learning how to do some of the things we learned how to do using Minitab last semester.  Stata will do quite a bit more than Minitab, but it is a little harder to learn.

Stata

We are using Stata for computations in this course.  
The following information is on Ron Schrader's homepage


Package Documentation Availability (as far as I know) Useful links
Stata Old-fashioned printed manuals (online help is not enough) - Room 226 HSC library (for MPH - not public)
- 4 special computers in HSC library (for MPH - not public)
- 3 computers in MPH computing lounge in FPCT
 UCLA

To obtain Stata for your own use, you can order online at

 http://stata.com/order/new/edu/gradplans/gp-campus.html

We are using  Intercooled Stata 9 in the classroom.  I thought you could get by with Small Stata 9,  since we are not using very large data sets, but that did not pan out (Small will not handle even modest sized data sets).  You should get at least Intercooled Stata 9 (there is a larger more expensive edition also).  If you prefer the telephone, you may call Stata at 1-800-782-8272 and ask for Sales.  Please say that you want to purchase Stata under a grad plan at the University of New Mexico and tell them which of the options (from the link above) you want to pay for and what type of operating system you will be using to run Stata (MAC, Windows or Unix -- most of you will want Windows). They will ask you for a credit card or means of payment and will send you a receipt by fax or email.  You will need an email address at unm (either a .unm.edu or salud.unm.edu will work - this is how they make sure you qualify for the educational pricing).  They will also notify Ms. Libby Henry at CIRT and you can pick up your order two business days later. Libby Henry's office is in the CIRT building at 2107 Campus Blvd (across from Hospital and East of the parking garage)
Ms. Henry's office is only open part-time. Please call or email ahead: ehenry@unm.edu277-8122.

Additional information from Lorraine Malcoe on 1/23:

Please let your class know that they have two options outside of class for accessing Stata 9 (if they don't purchase it through the UNM GradPlan). 
 
1) 4 'MPH' computers in the HSC library public area
2) 3 computers in the MPH computing lounge in the Family Practice Building.
 
I would still encourage them to purchase the software while they are a student because the savings is tremendous.

--- in response to my informing her I had suggested to you that the small version probably would be adequate:

I agree if they are only planning to purchase a one-year license.  But, if they will be purchasing a perpetual license (which we encourage our MPH epi concentration graduates to do) then they should purchase intercooled Stata 9. 
 
We won't be offering our epi data analysis class until fall 2007.  If students plan to take that class then it would be best for them to get intercooled stata 9 with a perpetual license - they'll need intercooled for the size of the datasets used in that class (and they might need it for data sets that they might analyze during their MPH Practicum experience, if they focus on data analysis).  If they just want Stata for the purposes of your class then they can purchase the small stata (which is only for one year).
 
They should all purchase through the UNM gradplan.
