On maximal ancillarity

1989
Conditional completeness is shown to provide a sufficient condition for maximal ancillarity. Using properties linking ancillarity and complete sufficient statistics, the new condition is shown to be more general than another sufficient condition given by Basu (1959).

ANCILLARITY AND MINIMAL SUFFICIENCY

Australian Journal of Statistics, 1983
SummaryA discussion of ancillarity in multinomial distributions provides the context for an example which queries the priority of the Sufficiency Principle.

Successive improvement of the order of ancillarity

Biometrika, 1986
SUMMARY It is shown by an argument similar to one of Welch (1947) that it is, under usual regularity conditions, in general possible to improve the order of ancillarity successively. This means that when an asymptotic ancillary has been constructed, such that its distribution is independent of the parameter apart from terms of order O(n- k), then a new

Extensions of the Concept of Local Ancillarity

Biometrika, 1981
SUMMARY Cox (1980) introduced a notion of local ancillarity. In this paper, a qth order local ancillary variable is defined; the idea of local ancillarity for the multiparameter model with no nuisance parameters is developed for inference and third-order local ancillarity is examined in the single parameter model.

S-Ancillarity and Strong Exogeneity

2000
This note analyses the differences and similarities between the concepts of Sancillarity and strong exogeneity. We show that while strong exogeneity of a variable for a parameter implies S-ancillarity of the same variable for the same parameter, the converse is not true. An example illustrates the point.

Godambe's paradox and the ancillarity principle

Statistics & Probability Letters, 1987
In this paper two types of statistical inference are defined, for only one of which Godambe's ancillarity principle [\textit{V. P. Godambe}, J. Am. Stat. Assoc. 77, 931-933 (1982; Zbl 0512.62008)] is seen to hold, although Godambe's mode of inference exhibits a high frequency performance.

On information and ancillarity in the presence of a nuisance parameter

Biometrika, 1983
This paper discusses ancillarity, in the presence of a nuisance parameter. For exponential distribution families, some equivalent properties regarding ancillarity are found and discussed.

Civilizzazione e funzione ancillare della forza

SOCIOLOGIA DEL DIRITTO, 2022
A very respectable theory (K.R. Popper) argues that civilization tends to limit the use of violence and opposes a state of chaos, madness, barbarism and war. It is a philosophical theory that in its empirical validity can find a minimum (not exclusive) support from a triad of arguments.
