+### Influenza Illness
+
+The following estimation method is used for the `*_outpatient_flu` signals.
+
+For a fixed location $$i$$ and time $$t$$, let $$Y_{it}$$
+denote the Flu counts and let $$N_{it}$$ be the
+total count of visits (the *Denominator*). Our estimate of the influenza

 ### Day-of-Week Adjustment
 
 The fraction of visits due to COVID-19 is dependent on the day of the week. On
