getRI {refineR}

Method to calculate reference intervals (percentiles) for objects of class 'RWDRI'

Description

Method to calculate reference intervals (percentiles) for objects of class 'RWDRI'

Usage

getRI(
  x,
  RIperc = c(0.025, 0.975),
  CIprop = 0.95,
  pointEst = c("fullDataEst", "medianBS"),
  Scale = c("original", "transformed", "zScore")
)

Arguments

x

(object) of class 'RWDRI'

RIperc

(numeric) value specifying the percentiles, which define the reference interval

CIprop

(numeric) value specifying the central region for estimation of confidence intervals

pointEst

(character) specifying the point estimate determination: (1) using the full dataset ("fullDataEst"), (2) calculating the median model from all bootstrap samples ("medianBS"), (2) works only if NBootstrap > 0

Scale

(character) specifying if percentiles are calculated on the original scale ("or") or the transformed scale ("tr") or the z-Score scale ("z")

Value

(data.frame) with columns for percentile, point estimate and confidence intervals.
