title: Comparing spatio-temporal variations across multiple years
body: <p>I am new to spatial statistics. I am working on a project analyzing the spatio-temporal neonatal mortality. I have data for six year from 2012 to 2017 specified at district level per month. 
  How can I compare the spatial variation of neonatal mortality rate across the 6 years. I would want to be able to explain statistically the changes of the neonatal mortality rate either for each district or the country as a whole for the 6 year period.
  Any assistance would be greatly appreciated. Thanks!</p>
