WebbThe report is structured as follows. Section 2 gives a theoretical explanation why the CRPS can be estimated using weighted sums of Brier scores and quantile scores, for some suitable choice of weights. The weights will be selected empirically using a dataset of operational forecasts as follows. First, the Brier scores, quantile scores and CRPS ... WebbQuantile-Quantile Plots. Source: R/qqplots.R.

R: Quantile Quantile Plot

WebbWe consider a new approach in quantile regression modeling based on the copula function that defines the dependence structure between the variables of interest. The key idea of this approach is to rewrite the characterization of a regression quantile in terms of a copula and marginal distributions. http://www.python88.com/topic/119751

Webb3.1. Quantile-regression-based models Quantile regression is a common and useful approach to achieving quantile forecasts and is especially easy to take advantage of exogenous information, such as holidays, seasonality, and policies.

If the resulting plot is linear, then the sample data likely comes from the specified distribution.

WebbThe quantile quantile plot consists of plotting the observed quantiles in function of the theoretical ones. The theoretical quantiles Q_ {Theo, j} QT heo,j are computed from the fitted GPD, that is: Q_ {Theo, j} = F^ {-1} (p_j) QT heo,j = F −1(pj) where F^ {-1} F −1 is the fitted quantile function and p_j pj are empirical probabilities defined by : Webb3.2 Theoretical Distribution.
