Dear community, I am replicating a paper (The Effect of Structures and Power on State Bargaining Strategies, http://tinyurl.com/oyk289c) for a class project. The author used ?gologit? in STATA, and I need the equivalent function in R. She used a ?Generalized Ordered Logit? (see below model description). Can you run a ?generalized ordered logit? with glm? I could not find the specification in the help file for the function. Or is there another R package for it? The data can be accessed here: http://tinyurl.com/oydwl4d (McKibben_AJPS Bargaining Strategies data.tab) The results should look like this: http://s17.postimg.org/3zldxs133/Brooke.png Thank-you so much for your help. It is greatly appreciated. Kind Regards, Brooke Model Description from the original paper: To test the effects of the bargaining structure against more standard explanations of variation in state bargaining behavior, I estimate two generalized ordered logit models with clustered standard errors. Model 1 includes lnGDP, focusing on states capabilities as the central measure of their power, and Model 2 includes the alternative, Voting power index. While standard ordered logit models might appear to be the appropriate statistical technique, the data violate the assumption of proportional odds that underpins these models. In other words, all independent variables do not exert the same effect across all categories of the dependent variable. The generalized ordered logit model relaxes this assumption, allowing the effects of the independent variables to vary across the different cate- gories of cooperative bargaining behavior. Standard er- rors were also clustered by negotiation phase to deal with the fact that each state?s choice of bargaining behavior within a given bargaining interaction is dependent on the choices of other states. (These models were estimated using the gologit2 command in Stata)
