Parameter recovery in two-component contamination mixtures: the ${\mathbb{L}}^2$ strategy

Sébastien Gadat, Jonas Kahn, Clément Marteau +1

In this paper, we consider a parametric density contamination model. We work with a sample of i.i.d. data with a common density, $f^{\star }=(1-{\lambda }^{\star })\varphi +{\lambda }^{\star }\varphi (.-{\mu }^{\star })$, whe…
