SAS 6: Computing SMR

Standardized Mortality Rate by Strata

This assignment teaches you a little more about reading in data with SAS and also how to compute standardized mortality rates both overall and by strata.

In Part A, you will compute the SMR for skin cancer and compare that to the US as the reference population. In Part B, you will compute the SMR stratified by age. Complete code is given below. Refer to the link in the livebinder for a video explaining each statement.

1. Run the code for the two analyses.

2. Answer this question referring to your results? Does the first analysis show a difference in SMR for skin cancer between Florida and the US as a whole?

3. Answer this question referring to your results? Does the second analysis, by strata, show a difference in SMR for skin cancer between Florida and the US as a whole?
