▁two ▁" possible " ▁true ▁values ▁of ▁the ▁re venue ▁are ▁also ▁displayed ▁at ▁a ▁distance ▁from ▁the ▁estimate . ▁ ▁As ▁indicated ▁by ▁the ▁picture , ▁since ▁info - g ap ▁robust ness ▁model ▁applies ▁its ▁Max imin ▁analysis ▁in ▁an ▁immediate ▁neighborhood ▁of ▁the ▁estimate , ▁there ▁is ▁no ▁ass urance ▁that ▁the ▁analysis ▁is ▁in ▁fact ▁conducted ▁in ▁the ▁neighborhood ▁of ▁the ▁true ▁value ▁of ▁the ▁re venue . ▁In ▁fact , ▁under ▁conditions ▁of ▁severe ▁uncertainty ▁this — method olog ically ▁speaking — is ▁very ▁unlikely . ▁ ▁This ▁ra ises ▁the ▁question : ▁how ▁valid / use ful / mean ing ful ▁are ▁the ▁results ? ▁Ar en ' t ▁we ▁swe eping ▁the ▁sever ity ▁of ▁the ▁uncertainty ▁under ▁the ▁car pet ? ▁ ▁For ▁example , ▁suppose ▁that ▁a ▁given ▁ ▁allocation ▁is ▁found ▁to ▁be ▁very ▁frag ile ▁in ▁the ▁neighborhood ▁of ▁the ▁estimate . ▁Does ▁this ▁mean ▁that ▁this ▁allocation ▁is ▁also ▁frag ile ▁elsewhere ▁in ▁the ▁region ▁of ▁uncertainty ? ▁Con vers ely , ▁what ▁guarantee ▁is ▁there ▁that ▁an ▁allocation ▁that ▁is ▁robust ▁in ▁the ▁neighborhood ▁of ▁the ▁estimate ▁is ▁also ▁robust ▁elsewhere ▁in ▁the ▁region ▁of ▁uncertainty , ▁indeed ▁in ▁the ▁neighborhood ▁of ▁the ▁true ▁value ▁of ▁the ▁re venue ? ▁ ▁More ▁fund ament ally , ▁given ▁that ▁the ▁results ▁generated ▁by ▁info - g ap ▁are ▁based ▁on ▁a ▁local ▁re venue / al location ▁analysis ▁in ▁the ▁neighborhood ▁of ▁an ▁estimate ▁that ▁is ▁likely ▁to ▁be ▁substantial ly
