1 The serial interval (SI) is NOT one of the estimators.
3 <p>The SI is a parameter required by all of the estimators, and can also be estimated by the WP method.

5 <p>The SI is defined as the average time between successive infections in a chain of transmission i.e., the time between the infection of an infected and their subsequent transmissions.
</p>
7 <P> Make the tab a different shade (light gray) and then this won't have parameters. It will let us not have to explain SI every single time. We'll expand the description later.
