Learn how to calculated stratum-specific frequencies by asthma status, and add these results to the categorical Table 1 for presentation.
- [Instructor] Now we move on…to complete our categorical table one.…Welcome to chapter five section six.…Remember, we just made frequency code overall…for univariate frequencies of the exposure…in each confounder.…So we can use that code as a template.…It has a nice macro we can copy in it.…Next, I'm going to show you how to run…separate bivariate frequencies for the portion…of the data set where people report having asthma…and then for the rest of the data set,…the no asthma people.…
As we did before, we will output CSVs…and then copy paste the results…into the categorical table one shell.…Let's go look at our categorical table one…and see how it's doing.…As you can see, we need to fill in…Freq Asthma and Freq No Asthma.…Remember for each of these,…the denominator of the percentage is the column total,…having asthma or not having asthma.…So what are we going to do?…Reuse our code.…
See these freqs in our Data folder.…Let's just erase all these freq CSVs.…We don't need them now.…They were our overall freqs…and we already got the data off of them in earlier sections.…
This detailed, practical course is designed to help those in the field of public health, medicine, and data science to edit, analyze, and interpret data. Learn how to code new variables, use the forward-stepwise modeling process, and document your decisions. Find out how to visualize results by generating charts and graphics, and how to add tables and figures to your documentation. This course helps equip you to independently design, develop, and execute a full BRFSS analysis, and even publish your results in scientific publications or journals.
