Primary and Secondary Syphilis Growth Rates Over Time

Growth Rates by County

Where are the counties with the highest growth rates located?

To answer this question we fit a Bayesian growth curve model to the data and extract the county-specific year coefficients. Random effects are included for each county to account for county-specific variation in growth rates.
