文摘

In the linear regression quantile model, the conditional quantile of the response, Y, given x is Q_Y|x(τ)≡x^′β(τ). Though Q_Y|x(τ) must be monotonically increasing, the Koenker–Bassett regression quantile estimator, 90be3302c4246964de7ca567b21f7b9c"">, is not monotonic outside a vanishingly small neighborhood of b36c0ffc"">. Given a grid of mesh δ_n, let be the linear interpolation of the values of 0b347afacd5fa590a02ce73""> along the grid. We show here that for a range of rates, δ_n, will be strictly monotonic (with probability tending to one) and will be asymptotically equivalent to in the sense that n^1/2 times the difference tends to zero at a rate depending on δ_n.
