Graphical Trends
From analyzing the graph, yearly death rates attributed to most causes are on the decline. However, unintentional injuries, suicide, and Alzheimer's disease have seen a slight increase each year.
Lower death rates for most cases shouldn't come as a surprise thanks to enhanced medicine over the years.
As for unintentional injuries and suicide, the rise has been attributable to primary rural regions of America. This is in part attributable to the lower availability of critical access hospitals, higher insurance costs in rural areas, and a higher percentage of population without health care insurance. This means that those who require medical attention for their conditions are unable to get the help they need in a timely manner.
Moreover, during 2005 states around the Gulf of Mexico see slightly larger increases in death rates attributable to Huricane Katrina
Alzheimer's disease has also seen a general rise in more populated areas; indicative of higher elderly populations in the dense urban areas.
MACHINE LEARNING APPROACH
To create a model of average age-adjusted death rate (R) across America, raw data collected across disease types were used to create a linear regression algorithm. Every year from 1999 to 2016 was included the dataset. In coding the algorithm, five variables were accounted for: intercept of age-adjusted death rate, the coefficient relating the change in age-adjusted death rate each year, the mean absolute error, mean squared error, and the mean squared standard deviation.
