On m-processes and m-estimation

WebM-estimators are solutions, θ, which minimize This minimization can always be done directly. Often it is simpler to differentiate with respect to θ and solve for the root of the … Webwhich allows one to handle weighted empirical processes. Also the concentration inequalities (see e.g. [9]), which consider the concentration of the supremum of the empirical process around its mean, are extremely useful in M-estimation problems. A more recent trend is to derive non-asymptotic bounds for M-estimators. The
