Strong uniform consistency rates of conditional quantiles for time series data in the single functional index model

The main objective of this paper is to estimate non-parametrically the quantiles of a conditional distribution when the sample is considered as an $\alpha$-mixing sequence. First of all, a kernel type estimator for the conditional cumulative distribution function ({\em cond-cdf}) is introduced. Af...
