Like the distribution function, the quantile function provides a complete description of the statistical...
2.2 Quantile function (QF) Hyndman and Fan [18] first proposed the notion of a quantile function (QF). The quantile of LE-IE model is presented here, including a few usages. The quantile function of a distribution has several uses in both theoretical and applied statistics, including means ...

Specific elements in the range of a variate are called quantiles, and denoted (Evans et al. 2000, p. 5). This particular meaning has close ties to the so-called quantile function, a function which assigns to each probability attained by a certain probability density function a value defined...
The summary statistics for the variables are shown in Table 1 below. Table 1 Summary statistics. Full size table Empirical methodology The study makes use of a number of panel estimation techniques for the empirical analysis. The panel two-stage least squares (2SLS) technique was used as the ...

In the sequel, we show that performance guarantees can still be derived for the check loss as well as other non-Bregman loss functions. What is key for the guarantees to hold is a notion akin to stochastic equicontinuity of the loss function. 2.3 Estimation As usual in the CAViaR literature...
