The price of gold has risen dramatically since 2001 and there have been intense debates regarding the current price of this asset and its long-term outlook. Here we study a long history of the price of gold and construct a quantile regression model to identify distributional relationships...

We consider several variants of a likelihood-ratio process for quantile regression designed to test composite hypotheses about the combined influence of several covariates over an entire range of conditional quantile functions. A closely related process is proposed as a goodness-of-fit criterion...

Quantile regression has emerged as an essential statistical tool of contemporary empirical economics and biostatistics. Complementing classical least squares regression methods which are designed to estimate conditional mean models, quantile regression provides an ensemble of techniques for...
