Design and Analysis of Probability Surveys

Duration: 3.0 days CEU: 1.8

This course focuses on designing business and household surveys and analyzing data collected under complex survey designs. The course addresses the SAS procedures SURVEYSELECT, SURVEYMEANS, SURVEYREG, SURVEYFREQ, and SURVEYLOGISTIC.

Learn how to

select complex samples using the SURVEYSELECT procedure
estimate descriptive statistics using the SURVEYMEANS procedure
estimate frequencies and percentages using the SURVEYFREQ procedure
fit general linear models using the SURVEYREG procedure
fit logistic regression models using the SURVEYLOGISTIC procedure
assess fitted linear/logistic regression models.

Who should attend

Survey statisticians, biostatisticians, epidemiologists, and social scientists who design and analyze data from complex probability surveys

Prerequisites

Before attending this course, you should

be able to execute SAS programs and create SAS data sets. You can gain this experience by completing the SAS Programming I: Essentials course.
have completed a course in statistics that covers linear regression and logistic regression. You can gain this experience by completing the Statistics I: Introduction to ANOVA, Regression, and Logistic Regression course.

Classroom Course Materials

Students receive a hardcopy of the course notes and, in some courses, can choose to take home a copy of the course data.

Live Web Course Materials

Students attend Live Web classes using a Web browser and a telephone and interact with their instructor and fellow classmates in real time. Each student receives an e-mail with instructions on how to join the class three business days before the class begins. The instructions e-mail includes a link to download the course materials, including the exercise files. Students need to download and print the course materials prior to class.

System Requirements

For Live Web, you must

review and follow the general system requirements.
complete the course exercises through our virtual lab. The virtual lab allows you to access the software used in class over the Internet, so that you do not need this software on your local machine.
run this test to connect to a virtual lab session. If firewall problems prevent you from connecting to the virtual lab, then you will need the following software installed and configured in your environment to participate in the course exercises:
- Base SAS 9.2 or 9.1.3 on a Windows operating system or SAS Learning Edition.
  Important: Students using SAS Learning Edition will need to create a shortcut to the SAS windowing environment (SAS Explorer, Enhanced Editor, Log, and Output windows) for use during the class. Follow these instructions for creating a shortcut to SAS prior to class.
