WebThe primary benefit of {cmd:craggit} is that it facilitates interpretation of results. {pstd} As with {cmd:tobit}, there are three primary values of interest extending from the results of {cmd:craggit} estimation (if y is {it:depvar2} and x is all the variables in {it:indepvars1} and {it:indepvars2}): {pin} (1) P [y>0 x] {space 5} (the … WebIn this article, I introduce the user-written command craggit, which simultaneously fits both tiers of Cragg’s (1971, Econometrica 39: 829–844) "two- tier" (sometimes called "two-stage" or "double-hurdle") alternative to tobit for corner-solution models. A key limitation to the tobit model is that the probability of a positive ...
