Join Monika Wahi for an in-depth discussion in this video Reviewing existing literature for ideas, part of Healthcare Analytics: Regression in R.
- So far, you've made it to chapter one,…section three,…where I wanted to spend just a little time…talking conceptually about selecting a topic…for your BRFSS analysis,…mainly through reviewing what other topics…have already been studied and published…about the BRFSS.…So, I selected two example papers…that use BRFSS data sets from various years…to answer questions.…I have no connection with any of these papers.…I just found them in the literature,…and will use them as examples.…
These two papers are posted in your resources,…but in this lecture,…instead of focusing on the nuts and bolts…of operationalizing these components of this hypothesis,…as we have gone over,…I will instead focus on the big picture…of how these authors came up with the idea…to do this analysis and write this paper.…After all, the papers were so compelling…they even were able to get them published.…So let's think about what they did.…Let's turn our attention to the first one,…which is by Mukherjee and Segal in 2015…about discussions with healthcare providers…
