ucateg: draws from a categorical distribution

In prr: generalized probabilistic range ranker

Description

Following the description given in /prr/ document, returns draws from a so-called categorical distribution defined by the lim vector of limits. The number of limits must be greater or equal to 3. The returned values are in between the two extreme limits.
The number of returned draws is max(length(mu),length(coefvar)). When both lengths are not equal, the smaller one must be equal to one, if not an error is issued.
NA value are possible in mu and coefvar, then missing values are returned for the considered draws.

Usage

ucateg(mu, coefvar, lim)

Arguments

mu	numeric vector of the expectations. From it the central limit is choosen.
coefvar	numeric vector of coefficients of variation. Either a common value for every draws, or a value for each of the draws. Cannot be negative.
lim	vector of the ordered limits; at least three limits. The limits are common for all draws.

Details

Extensive use is made of the function ubeta.

Value

A vector of the drawn values, possibly containing NA.

Examples

 prr3k("RESET"); # For R checking compliance
 set.seed(1234); 
 ucateg(round(10*runif(25)), 30, 1:10);
