nonparRI {referenceIntervals}

Determines the reference interval using non-parametric means

Description

This function uses the appropriate percentiles as determined by refConf to return the non-parametric reference interval. This is written as a boot function to use within the function refLimit.

Usage

nonparRI(data, indices = 1:length(data), refConf = 0.95)

Arguments

data

data is a vector of sample values.

indices

The indices of data to be used in the calculations. The default is to use the whole set.

refConf

refConf is a measure of the range covered by the calculation. Most often, as is the default, 95

Value

Returns a vector of two values, the lower and upper limits of the reference interval.
