Help needed to find appropriate methodology..

Hello all,

I am working on a marine data project. I have the accident locations ( Lat/long) as points. I also have lines for the ship routes, But the dataset is a mixture of nominal, ordinal,ratio data. I was thinking to divide the data into different seasons.

I want to find out the root cause of accident and to see if there is any spatial dependency in accident locations.

Please help me with some ideas if you have. Can you please help me with point pattern analysis? How can I apply it here?

Looking forward..
