1 In oduc ion
Classical wo-sample compa isons be ween wo popula ions ha e ex ensi e
applica ions in many scien i ic ields, including con olled expe imen s,
biome y, psychology and indus y. Many es s exis in he li e a u e o assessing
he di e ence in a ious pa ame e s be ween wo independen popula ions.
Fu he mo e, he da a used in con ol expe imen s canno accu a ely es ima e he
popula ion dis ibu ion because he sample size is oo small, he e migh be a ew
ou lie s, o i could be a con amina ed sample. A nonpa ame ic es is p e e able
he e, as we canno assume no mali y o any o he speci ic dis ibu ion.
Many esea che s ocus on designing a es o he di e ence in a single
pa ame e , such as he loca ion, scale, o shape pa ame e in a dis ibu ion- ee
se up. Fo example, he mos amous es s o he wo-sample loca ion p oblem
in he dis ibu ion- ee se ing a e he Wilcoxon ank-sum es (Gibbons &
Chak abo i, 2021), namely
W
, o he no mal sco es es (Gibbons & Chak abo i,
2021). Assuming ha he popula ion dis ibu ion is no mal, he asymp o ic
ela i e e iciency (ARE) o he Wilcoxon ank-sum es and he no mal sco es
es ela i e o he es a e 0.955 and 1, espec i ely, indica ing ha hey a e
no in e io o he es . In addi ion, he ARE o he Wilcoxon ank-sum es o
he es is g ea e han o equal o abou 0.864 o all con inuous dis ibu ions.
The e o e, he Wilcoxon ank-sum es is s ill widely u ilized in many
applica ions, see. e.g. Le shedi e al. (2021), Lin e al. (2021) and Dao (2022).
The pa ame ic wo-sample es o es ing he a iances o he no mal
dis ibu ion is he F es . The Ansa i–B adley, namely
AB
, and Mood es s
(Gibbons & Chak abo i, 2021) a e well-known nonpa ame ic es s o he wo-
sample scale p oblem. The ARE o he Ansa i–B adley es and he Mood es
o he F es unde he assump ion o he no mal dis ibu ion a e 0.609 and 0.76,
espec i ely. Al hough ARE o he Ansa i–B adley es is lowe han ha o he
Mood es , he Ansa i–B adley is widely used in many applica ions, see, e.g.
Lahmi i (2023) and Ome e al. (2023). The wo loca ion es s, based espec i ely
on Wilcoxon and an de Wae den’s no mal sco es o wo-sample p oblems,
assume no scale di e ence in he popula ion dis ibu ions. Likewise, he wo
scale es s, based espec i ely on Ansa i–B adley and Mood sco es o wo-
sample p oblems, assume no loca ion di e ence in he popula ion dis ibu ions.
Ac ually, he e a e o en di e ences in bo h loca ion and scale in many p ac ices.
Many esea che s ocus on designing a es o he di e ence in loca ion and
scale pa ame e s be ween wo popula ions simul aneously in a dis ibu ion-
ee se up. The mos well-known es s in his ci cums ance, he es o he
loca ion and scale simul aneously, a e he Lepage (Neuhäuse , 2012) and he
Cucconi (Neuhäuse , 2012) es s. The Lepage s a is ic combines he squa e
o he s anda dized Wilcoxon ank-sum and he s anda dized Ansa i–B adley
s a is ics. The Lepage- ype s a is ic, which is a quad a ic o m o loca ion and
scale s a is ics, has been s udied by many esea che s. Fo example, Pe i (1976)
p oposed he combina ion o he squa e o s anda dized Wilcoxon ank-sum and
he squa e o s anda dized Mood s a is ics. No e ha he s a is ic o Pe i (1976)

is essen ially equi alen o he s a is ic o Cucconi (Neuhäuse , 2012) unde he
con inuous dis ibu ions; see Nishino and Mu akami (2019). Since Mu akami
(2011) p oposed an app oxima ion o he dis ibu ion o he s a is ic o Pe i
(1976), we can apply he app oxima ion dis ibu ion o he Cucconi s a is ic.
Fo di e en e sions o Lepage- ype s a is ics, we e e o wo ks o Büning
and Thadewald (2000), Neuhäuse (2000), Kössle (2006), Mu akami (2007),
Mu akami (2016) and Mukhe jee and Ma ozzi (2019). Recen ly, Yamaguchi and
Mu akami (2023) discussed mul i-aspec s a is ics gene alizing he Lepage- ype
s a is ics in he p esence o ies.
Kössle and Mukhe jee (2020) ecen ly no ed ha adi ional wo-sample
simul aneous es s o loca ion and scale pa ame e s a e silen abou he shape o he
dis ibu ions. A change in he shape o he dis ibu ion in a wo-sample p oblem is
add essed using he Lehmann al e na i e (Hájek e al., 1999) and is e y common in
many applica ions, see, e.g. Razzaghi (2014), Ng e al. (2021) and Chak abo y e al.
(2023). Fo he Lehmann al e na i e, o example, he An i-Sa age es (Kössle &
Mukhe jee, 2020), namely
AS
, is widely used by many esea che s. Howe e , he
di e ence in a single pa ame e is a e in many applica ions. I is mo e gene al and
ad isable o conside ha a he same ime, a shi may occu in one o mo e o he
h ee pa ame e s, namely, loca ion, scale, and shape pa ame e s. The e o e, we mus
ocus on designing app oaches o simul aneously es ing many pa ame e s be ween
wo popula ions. No e ha Kössle and Mukhe jee (2020) only conside he squa es
o Euclidean and Mahalanobis ype dis ance be ween he Wilcoxon, Ansa i–B adley
and An i-Sa age s a is ics. The An i-Sa age es is sui able o di e ence in loca ion
o he igh -skewed da a.
Howe e , we some imes encoun e le -skewed da a in p ac ical analysis. In
his case, he Sa age es , namely
S
, is one o he p e e ed es s. In he heo e ical
backg ound, he Sa age es is he locally mos powe ul ank es o he le -skewed
Gumbel dis ibu ion. Then, we may conside simila combina ions using Wilcoxon,
Ansa i–B adley and Sa age s a is ics. Also, he null dis ibu ion may be symme ic,
bu he shape al e na i e could lead o a igh o le -skewed popula ion, and he
shi di ec ion is unknown a p io i. Then, a ques ion ega ding he choice be ween
hese a ises and is add essed in he cu en pape .
Recen ly, Yamaguchi and Mu akami (2023) p oposed he ie-adjus ed e sion
o he Euclidian and Mahalanobis dis ance-based s a is ics o some s anda dized
linea ank s a is ics, ha is he mul i-aspec es s. Howe e , in p ac ical analysis,
we mus de e mine whe he o use he Wilcoxon–Ansa i–B adley–An i-Sa age
s a is ic o he Wilcoxon–Ansa i–B adley–Sa age s a is ic be o e we ea he
hypo hesis es . To his end, we migh conside a max- ype es . The la ge o he
wo s a is ics as he es s a is ic is he i s and simple way o sol e his p oblem.
Fo example, Neuhäuse e al. (2004) and Welz e al. (2018) compa ed he alidi y
o he maximum es wi h a ious nonpa ame ic es s o he wo-sample loca ion

also conside an adap i e es , which selec s he es s a is ic depending on he case

scale p oblem, Kössle (1994) p oposed he adap i e es based on new selec o s

he wo-sample loca ion p oblem by using he selec o s o Hogg e al. (2018,pp.
622–623). Fo he one-sample loca ion p oblem, ecen ly, Ki ani and Mu akami

Mu akami (2023) conside ed he mul i-aspec es s a is ic based on some linea ank
