DESCRIPTION: Likelihood p-values and ancillaries have been around for\nmuc
 h longer than most would acknowledge\, yet continue to be clouded by\nlack
  of agreement and direction. Asymptotics from Daniels to\nBarndorff-Nielse
 n has has extended core versions to give highly\naccurate approximations i
 n more general contexts\, but with variable\nand parameter essentially of 
 the same dimension. More recently the\nvector quantile function obtained b
 y inverting coordinate distribution\nfunctions to coordinate quantile func
 tions has clarified the role of\ncontinuity and enabled the further extens
 ion to sample spaces with\ndimension larger than the parameter.  We survey
  these developments and\ndiscuss two examples\,\nnonlinear regression and 
 Cauchy analysis\; equivocal results are resolved.\n
