Abstract : This article, by obtaining the limit of probability that some equation arising in a case of Mestimate possesses at least one solution, establishes the fact that even in the simplest case, when the function rho is not differentiable at least at one point, it is not legitimate to convert a minimization problem defining the Mestimate to the solution of equations.
