SPSS question, really. Been asked to produce two simple linear regression models, one with an intercept, one without (both for one set of data points). But they have to be on one scatter plot for comparison. I'm new to SPSS so if somebody could help me out with the command prompts, I'd really appreciate it. Thank you.
