I tried upon the little knowledge of the spread of the disease that we have.
I am studying Laurel wilt spread in avocado groves. I want to see if there are any trends in the spreading, based on time and space. I would like to answer the question if it is only spreading from avocado tree to avocado tree or if there is a continuous inlet from outside the avocado growing area.
That's why i wanted to do a spatial weights matrix and than a grouping analysis, to see if the data inside the growing zone is closely related.
I don't know if it is the best way to answer the question.
