71_quantile-based_summaries: Order-Based Summary Statistics

In probhat: Multivariate Generalized Kernel Smoothing and Related Statistical Methods

Description

Compute named sequential quantiles, primarily for producing summary-style output.

Usage

ntile.names (n, symbol="q", ..., emph = n / 2)

quartiles (xf, col=FALSE, ...,
    prob=FALSE, names = ntile.names (4, "Q", emph=emph), emph=2)
deciles (xf, col=FALSE, ...,
    prob=FALSE, names = ntile.names (10, "D", emph=emph), emph=5)

ntiles (n, xf, col=FALSE, ..., prob=FALSE, names)

Arguments

n	Integer, the number of sequential quantiles.
symbol	String, letter/symbol for the quantile names.
xf	A numeric vector, suitable function object, or an object that can be coerced to a numeric vector. Here, a suitable function object is a quantile function. Refer to the references and see also sections.
col	Logical, if true, return a single-column matrix.
prob	Logical, if false (the default), name quantiles by index/names, if true, name quantiles by probability.
names	Character vector, giving the names. Ignored, if rank is false.
emph	In principle, an integer vector in 1:(n-1), which quantiles to emphasize. Can also be a numeric vector, but the floor/ceiling values are used.
...	Other arguments. Refer to details.

Details

If xf is a numeric vector, a qfuv.el object is created using xf as the main argument.
Any arguments contained within ..., are passed to the qfuv.el constructor.

If xf is not a quantile function, these functions try to coerce it to a numeric vector, and apply the above.

Value

ntiles.names returns a character vector.

The other functions return a named numeric vector (if col=FALSE), or a named single-column matrix (if col=TRUE).
