3.9 Consider the equationimage text in transcribed

where C is the Cauchy likelihood function (3.18). Denote Kn as the number of its roots. If X1, . . . ,Xn are independent, identically distributed with the Cauchy C(0, 1) distribution, then Kn − 1 has asymptotically Poisson distribution with parameter 1 , as n ! 1. (See Barnett (1966) or Reeds (1985)).
