A famous example in genetic modeling (Tanner, 1996 or Dempster, Laird, and Rubin 1977) is a genetic linkage multinomial model, where we (+(1-0), (1 0), ). observe the multinomial vector (xq, X2. X3. X4) with cell probabilities given by (a) Show that this is a curved exponential family. (b) Find a sufficient statistic for e. (c) Find a minimal sufficient statistic for e.
