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. ADVERTISEMENTPopular Course in this ca...
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 ...
Quantiles play a fundamental role in statistics. The quantile function defines the distribution of a random variable and, thus, provides a way to describe the data that is specular but equivalent to that given by the corresponding cumulative distribution function. There are many advantages in working...
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 ...

In statistics, a quartile is a type of quantile which divides the number of data points into four parts, or quarters, of more-or-less equal size. The data must be ordered from smallest to largest to compute quartiles; as such, quartiles are a form of order statistic. Quantile Each of...
[Springer Texts in Statistics] Probability for Statisticians || Distribution and Quantile Functions We provide sufficient conditions under which the center-outward distribution and quantile functions introduced in Chernozhukov et al. (2017) and Hallin (2017) are homeomorphisms, thereby extending a recent...
