Regression Concepts
Simple linear regression is another method
used to explore the relationship between two
continuous variables.
The main difference between correlation
analysis and simple linear regression is that

Multiple Logistic Regression
Multiple logistic regression allows us to
have more than one predictor in our
model.
Allows us to estimate the association
between each predictor and CHD
evidence, controlling for all other
predictors.

There are different types of variables.
Different variable types require
different statistical procedures.
Choosing the correct statistical

Validity
Epidemiologic studies usually compare the
frequency of disease (outcome) in two (or
more) groups according to a characteristic
of interest (exposure).
Use measures of association (risk ratios
and odds ratios).
