Abstract: | Let X
1,...,X
n
be an i.i.d. sample of random curves, viewed as Hilbert space valued random elements, with mean curve m. An asymptotic test of m = m
0 vs m ≠ m
0 is proposed, when m
0 is a fixed known function. The test statistics converges under very mild assumptions and relies on the pseudo-inversion of
the covariance operator (leading to a non standard inverse problem). The power against local alternatives is investigated.
