Probability Surveys 1: Design, Descriptive Statistics, and Analysis

This course focuses on designing business and household surveys and analyzing data collected under complex survey designs. The course addresses the SAS procedures POWER, SURVEYSELECT, SURVEYMEANS, SURVEYFREQ, SURVEYREG, SURVEYLOGISTIC, and SURVEYIMPUTE. In addition, the graphing procedures GPLOT, SGPLOT, and SGPANEL are also covered.

Aprenderá a

• calculate sample sizes using the POWER procedure
• 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
• handle missing value adjustment using SURVEYIMPUTE procedure
• implement balanced repeated replication, Taylor series and jackknife variance estimation
• perform domain analysis
• assess fitted linear/logistic regression models.
