Hello all, this will be a pretty straight forward question here. I am working with point data from earthquakes. I also am limited by my "trial" software. So in knowing that, what kind of analysis would you perform to gather statistics (not using excel) about your data? Lets say i want to know relationship of magnitudes,dept, location. ?? What tools would you use for this analysis? i also want to compare a second and thrid set of data to ensure my results are correct. Any suggestions would be helpful?
