WebbAbstract In this paper, we consider the so-called Shape Invariant Model that is used to model a function f0 f 0 submitted to a random translation of law g0 g 0 in a white noise. This model is of interest when the law of the deformations is unknown. Our objective is to recover the law of the process Pf0,g0 P f 0, g 0 as well as f0 f 0 and g0 g 0.
