Quantile function is used in MATLAB to divide a sample into adjacent, equal-sized subgroups. Quantile is also referred to as ‘fractile’, and in statistics, it is used to divide a given probability distribution into small areas which have equal probability. The median in statistics, for exampl...
Until now, however, no one put all the ideas together to form what turns out to be a general approach to statistics.Statistical Modelling with Quantile Functions does just that. It systematically examines the entire process of statistical modelling, starting with using the quantile function to ...
Although quantiles are not always unique, it is convenient in a mathematical sense to define a function that gives us a quantile for each probability. IfFis a distribution function — a function that takes a real numberxas input and returns the probability that a random variableXwill be less ...
Denoting by X1:n≤⋯ ≤ Xn:n the ordered sample, the non-parametric estimation of the quantile function is based on one or two order statistics. Here we consider the default non-parametric estimators given by the statistical package R. In this case, following Hyndman and Fan [9], the ...

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 ...

R语言内置函数(Built-in Functions) R中几乎所有的事情都是通过函数完成的。 下表提供了其它常用的统计函数。 R语言中每个数值运算函数都有na.rm选项,以便在计算前删除缺失值。否则,缺少值的存在将导致结果也是缺失值。统计函数的运算的对象可以是向量也可以是dataframe Function Description mean(x, trim=0, na.rm...
