Hi, I'm trying to figure out some stastistics for non-nested models testing. Among them: [1] Vuong statistic (Vuong, 1989) [2] Distribution-free test by Clarke (2003). Did someone wrote a piece of [R] code to compute any of them? Many thanks, Bruno ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bruno L. Giordano - Ph.
