64_random_number_generation: Random Numbers

Description

Generate random numbers (or synthetic data), univariate or multivariate.

Usage

rng (xf, n=1, …)

Arguments

xf

A numeric vector, suitable function object, or an object that can be coerced to a numeric vector. Here, a suitable function object is quantile function, or a chained quantile function. Refer to the references and see also sections.

n

Integer, number of random numbers.

…

Other arguments. Refer to the details section.

Value

A numeric vector, or numeric matrix.

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.

Note that the method used for multivariate random number generation is not efficient.

Refer to the vignette for an overview, references and better examples.
