Good questions
What is the NIS?
The National Inpatient Sample is part of the U.S. Healthcare Cost and Utilization Project (HCUP). It is the largest publicly available all-payer inpatient database in the United States.
Why do weighting and sampling matter?
The NIS is a sample of U.S. hospitalizations. Using its sampling structure and weights correctly is what turns it into valid national estimates, and it is a key part of this class.
What software will I use?
STATA. You will learn how to use it for NIS analysis during the class.
Do I need prior research experience?
A basic understanding of research helps. If you are completely new, our Level 1 workshop is a good place to start.
Will I work on a real project?
Yes. Every student is included in an NIS project with a mentor, with the goal of publishing in a high-impact journal.
How is it delivered?
Live on Zoom, with guided, hands-on training and Q&A throughout.
How much does it cost, and when is it?
The workshop fee is $120. Dates for the next cohort will be announced soon, so join the waitlist to hear first.
