Software Tips 1:
Moving Data to Excel

This tutorial demonstrates how to move saved SAS or Epi-Info output into Excel.  For practice, SAS and Epi-Info data sets,  SAS programs, and text files are available for download. 
Software Tips 2: Calculating IMR in SAS
This tutorial discusses software issues involved when calculating rates from individual level data. We demonstrate an approach in SAS for generating correct numerators and denominators, producing output with infant mortality rates on a per 1,000 basis.  In order to complete this tutorial, sample SAS datasets and SAS programs are provided.
Infant Mortality Trend Analysis
This skillbyte describes how trend analysis of infant mortality rates was carried out in Hawaii. Regression analysis was used to estimate trends for each of the seven main ethnic groups in the State, providing a more meaningful picture of infant mortality than was possible using unstratified data. A step by step description of how the analysis was carried out usingi Microsoft Excel is included.
Cumulative Teen Pregnancy
This skillbyte presents a method for calculating the cumulative risk of first time teen pregnancy.. The skillbyte discusses the conceptual basis for this measure, describes both its advantages and limitations, illustrates how to calculate it, and provides two ready-to-use Microsoft Escel workbooks that allow users to enter their own data and automatically calculate the cumulative risk of first time teen pregnancy.
