Imposing order constraint

Model x_2 using the GLM, and model delta instead of x_1 , such that x_1 = x_2 + delta . This makes sure x_1 > x_2 , but then I’m not sure how to interpret the distributions over the coefficients of the GLMs.

I would try with this. For interpretation of the coefficient you can always add the delta to x_1 and avoid interpreting the delta directly.
