Milan Meloun, Jiří Militký, in Statistical Data Analysis, 2011 G1: Quantile plot (x-axis: the cumulative (order) probability Pi; y-axis: the order statistic x(i)) The quantile plot permits identification of any peculiarities of the shape of the sample distribution, which might be symm...
The quantile score is frequently used in practical applications and data science competitions, e.g., in [100]. The pinball loss function can be decomposed in a similar fashion to the CRPS [92] using a discretization of the forecasts. The quantile score (QS) evaluates a single quantile τ,...
For duration data two fundamental features are censoring and time-varying regressors. The popular Cox proportional hazards model and other conventional duration models are highly restrictive in modelling how regressors affect the conditional duration distribution. Endogeneity such as selective compliance is al...

2a). In data science, graphs are often used to describe unstructured data like social networks, chemical molecules, and traffic networks. A typical graph is composed of several nodes and edges that indicate the connection relationship. As illustrated in Fig. 2a, Graph G expresses the plane ...

Additionally, the conventional DEA process can be viewed as a special case of qDEA in which q = 0 or α = 1 and no observed data points are allowed to be external to the qDEA-1 hyperplane. By endogenously identifying and allowing sets of external of points to be qDEA-α super...
Algorithms are proposed for the computation of set-valued quantiles and the values of the lower cone distribution function for bivariate data sets. These new objects make data analysis possible involving an order relation for the data points in form of a vector order in two dimensions. The ...
