Am I simply supposed to calculate it myself by taking the negative sum of the remaining part worths for that parameter?

Or am I missing something more important?

Thanks!

Joel,

The first level is removed to avoid multicollinearity issues but the centering of the utilities depends on the coding method. In CBC/HB we use effects coding by default which will zero-center the utilities. However in HB-Reg, the coding is dummy coding. Thus the value for the first level is assumed to be zero.
