Join Monika Wahi for an in-depth discussion in this video What you should know, part of Healthcare Analytics: Regression in R.
- [Instructor] Here is what you should know before taking this course. First, it's essential that you complete the first course in the series which is Descriptive Health Analytics in R. That's because this course will use the analytic data set developed in that previous course for demonstration. But in addition, you should have already had at least one course in basic statistics and that course should have at least touched on regression analysis. Also you should have a background in health, health care or public health.
However you don't need a heavy background in statistical programming. This is not so much a course on R perse, but a course that shows you how to use the forward stepwise modeling process to develop models that address hypothesis posed in health care and public health. We use R to make our deliverable, a completed regression analysis on the health care topic.
