TITLE: Comparing analytic and simulation approaches to parametric inference

Abstract:
Two routes most commonly proposed for accurate inference on a scalar 
interest parameter in the presence of a (possibly high-dimensional) 
nuisance parameter are parametric simulation (`bootstrap') methods, and 
analytic procedures based on normal approximation to adjusted forms of 
the signed root likelihood ratio statistic. Both methods yield 
higher-order accuracy, in the sense that, under some null hypothesis of 
interest, p-values are uniformly distributed to error of third-order in 
the available sample size. But, given a specific inference problem, what 
is the formal relationship between p-values calculated by the two 
approaches? We elucidate the extent to which the two methodologies 
actually give the same inference.
