Hello, I am a novice in SAS analysis. When using SAS to analyze complex sampling data, I found that when some proportions are small or large, the confidence interval is less than 0 or greater than 1, which is obviously impossible. Below is my code. What can I do to solve it? Drcat is a binary variable. I want to count its prevalence and confidence interval in the target population.
thank you !!!!!!!!!!!!
