Assignment #3  

 

 Data Comparison Using Empirical Bayes  

 

 

  This assignment focuses on data comparison from multiple sites with unbalanced sample size (with large disparity in data quantity between data sites). You need perform the following three tasks: 

 

1. Select 10 counties (the major metro areas must be included) identify fatal traffic crashes in each county. Crash data can be obtained by visiting their webpage and contacting the Ohio Department of Public Safety, if necessary.  

 

2. Select data for each county for the past 5 years to obtain the "within" variations and calculate the mean and standard deviation of each county. 

 

3. Use the Two Stage Normal Normal Model to estimate the statewide fatal crashes. The outcome of analysis is the overall crash assessment for Ohio from the past 8 years as well as the posterior (after adjustment) crash number for each county.
