Mastering Health Status Analysis with SAS: A Step-by-Step Guide
HealthPublic Health IssuesAnalyzing health status is crucial for understanding the factors that contribute to overall well-being. This article provides a comprehensive tutorial on using SAS to analyze health status, including summarizing the data and estimating ordered probit and ordered logit models.
Understanding the Variables and SAS Program
⭐️The dependent variable is health status, with three categories: fair, good, and excellent.
⭐️The independent variables include age, log income, and number of diseases.
⭐️The SAS program demonstrates reading the dataset, summarizing the data using proc means, and executing ordered probit and ordered logit models.
Estimating Ordered Logit Model and Interpreting Results
🔍Summarize the dependent variable and estimate the ordered logit model using SAS.
🔍Specify 'descending' when estimating the model to ensure correct interpretation of the probabilities.
🔍Coefficients indicate that higher income is associated with better health status.
FAQ
What are the categories of the dependent variable, health status?
The categories are fair, good, and excellent.
What does the SAS program demonstrate?
The program demonstrates reading the dataset, summarizing the data using proc means, and executing ordered probit and ordered logit models.
Why is it important to specify 'descending' when estimating the model?
Specifying 'descending' ensures correct interpretation of the probabilities in the ordered logit model.
What do the coefficients indicate in the ordered logit model?
The coefficients indicate the impact of independent variables on the likelihood of better health status.
How can proc qlim be used in the analysis?
Proc qlim can be used to estimate the ordered probit model and output marginal effects.
