New $M$ -estimators in semi-parametric regression with errors in variables

Cristina Butucea, Marie-Luce Taupin

In the regression model with errors in variables, we observe $n$ i.i.d. copies of $(Y, Z)$ satisfying $Y = f_{θ^{0}} (X) + ξ$ and $Z = X + ε$ involving independent and unobserved random variab…

Minimax and adaptive estimation of the Wigner function in quantum homodyne tomography with noisy data

Cristina Butucea, Madalin Guţa, Luis Artiles

We estimate the quantum state of a light beam from results of quantum homodyne measurements performed on identically prepared quantum systems. The state is represented through the…
