Calling Sequence

Decile(A, d, ds_options)

Decile(M, d, ds_options)

Decile(X, d, rv_options)

Parameters

A

-

data sample

M

-

Matrix data set

X

-

algebraic; random variable or distribution

d

-

algebraic expression or list of algebraic expressions; deciles

ds_options

-

(optional) equation(s) of the form option=value where option is one of ignore, method, or weights; specify options for computing the decile of a data set

rv_options

-

(optional) equation of the form numeric=value; specifies options for computing the decile of a random variable

Description

• 

The Decile function computes the specified decile of the specified random variable or data set.

• 

The first parameter can be a data set (e.g., a Vector), a Matrix data set, a distribution (see Statistics[Distribution]), a random variable, or an algebraic expression involving random variables (see Statistics[RandomVariable]).

• 

The second parameter d is a decile or list of deciles.

Options

  

For a description of the available options, see the Statistics[Quantile] help page. Calling Decile with decile d is equivalent to calling Quantile with probability 0.1d.

Examples
