-: Hi y'all, and welcome to module seven.
We are about halfway through the content of EPI2
so congrats for making it this far.
In the last module, we reintroduce confounding
and a lot of what you saw in that module
should have felt familiar from EPI1.
In this module, we will build on that discussion
and start talking about the ways
that we control for confounding.
We started this in EPI1 when we talked about stratification.
And if you remember,
we calculated stratum specific measures of risk
and then compared those
to understand if confounding was occurring.
In this module, we extend that
to talk about controlling for confounding
using multiple linear regression.
This is an advanced statistical technique
that allows you to control
for multiple confounders simultaneously.
To get to multiple linear regression,
we first need to learn about
simple linear regression and correlation,
which is where this module starts.
There's a lot of information this week,
lots to read, lots to watch, and lots to absorb.
So please give yourself plenty of time for this module.
This is not one that you'll wanna wait till the last minute
to get started on.
You'll also be learning how to apply these techniques,
possibly for the first time in SPSS.
So again, give yourself plenty of time to learn
and please reach out with questions.
Work with each other on Yellowdig,
tag me in a post or send me an email if you get stuck.
Take care and I'll see you next week.
