I'm needing help with multiple regression. I am very new to MR and have very little time in which to teach myself the essentials. I have access to SPSS 19. I am testing to see if the number of organized violent events (dependent variable) in a given location increases based on a series of independent variables - population increase (0 - no; 1 - yes); vegetation productivity (continuous); export ban (0-no ban; 1- ban); land degradation (0 - low degradation; 1 - high degradation); dominant livelihood (1- pastoral farming; 2 - agro-pastoral farming). How do I prepare my data and/or decide which variables I need to include in the MR? I have read so far that I need to test for multicolliniarity and hetroscedacity - how do I do this? And once I have done that what would be the next step(s)? You'd be a lifesaver for helping me out, my project had to be changed last minute (not my fault!) and this is what I've been given to do instead!
Please help! Thanks
