sorry, my notation is sloppy: the final expression should be in terms of x_i, z_i, \gamma, \beta, and y (there is no variable n, it's just an index for the number of observations . . ) EXL -- ERIC LIN Technology and Operations Management Harvard Business School Boston, MA 02163 elin at hbs.edu mobile: +1.216.225.2545 On Apr 10, 2010, at 6:09 PM, Lin, Eric wrote: for problem 1.2, should we be able to drop the d_i parameter for the final log likelihood? There are lots of variables here, so for a quick check, should the final expression be in terms of x, beta, z, \gamma y, and n? thanks!
