D. Siegmund et Hp. Zhang, THE EXPECTED NUMBER OF LOCAL MAXIMA OF A RANDOM-FIELD AND THE VOLUME OF TUBES, Annals of statistics, 21(4), 1993, pp. 1948-1966
Using an expression for the expected number of local maxima of a rando
m field, we derive an upper bound for the volume of a tube about a man
ifold in the unit sphere and show that under certain conditions our bo
und agrees with the evaluation of the tube volume in Weyl's formula. A
pplications to tests and confidence regions in nonlinear regression ar
e discussed.
