Nonparametric Method in Calculation of Reference Interval

This nonparametric method is used to calculate the reference interval when the distribution is skewed and the sample size is above to 120 observations.

Usage

nonparRI(x, ind = 1:length(x), conf.level = 0.95)

Arguments

x

(numeric)
numeric measurements from target population.

ind

(integer)
integer vector for boot process, default is all elements in x.

conf.level

(numeric)
the percentile of reference limit.

Value

a vector of nonparametric reference interval

Examples

data("calcium")
x <- calcium$Value
nonparRI(x)
#>  2.5% 97.5% 
#>   9.1  10.3
