# data crab; input color spine width satell weight; if satellgt;0 then y=1; if satell=0 then y=0; n=1; weight = weight/1000; color = color - 1; if...

Using the attached SAS program, you can run a logistic regression model of having a satellite with spine and weight as the two main effects predictors. Please demonstrate the equivalence of the Reference and Simple coding schemes by calculating the log odds ratio of having a satellite between group ( spine = 1) and group ( spine = 3 ) based on the SAS output of the two coding schemes.
