The director of the State Public Health Department wants you and your team to analyze data that the department has been collecting through the biosurveillance system. The director wants to know if you and your team are able to predict the occurrence of the new disease D, that you defined in the M8 Screening Tool Discussion. Pick a peer-reviewed article that utilizes the same statistical technique that you want to use to test your hypothesis. In a 250-word initial post, referencde must not be more than 5 years please address the following questions:What type of data do you need to extract from the biosurveillance system to formulate the prediction model? (Again, you can make any assumptions you need about the data collected in the biosurveillance system.)What prediction model will you be using and why? (Hint: When is it appropriate to use linear regression, multiple regression, and survival analysis?)Are there advantages or disadvantages of using your prediction model?
