In this article, we propose a semi-parametric mode regression for a non linear model. We use an expectation-maximization algorithm in order to estimate the regression coefficients of modal non linear regression. We also establish asymptotic properties for the proposed estimator under assumptions of the error density. We investigate the performance through a simulation study.

In this paper we consider the problem of non-parametric relative regression for twice censored data. We introduce and study a new estimate of the regressio
