I'm currently looking at rates for a study that vary between 0 and 100 with most of the rates falling between 0 and 1. I am running a linear regression on 70 dummy variables (coded 0-1) and nearly 100,000 lines of observations. When I run the regression, the coefficients I am getting for each of the dummy variables and intercept is in the region of 10E10 to 10E13. Testing the predicted values of this regression does come out to numbers around the actual rate (somewhere between 0 and 1 for the most part) but I feel like something is wrong with this analysis.
Is there something I might be missing as to why my coefficients for each variable are coming out so high? I'm new to actually implementing regression and don't know if anything is wrong or this is just the result I'm looking for. I'd really appreciate any help with this
