relInterIntra: Inter- and intra-rater reliability

Description

relInterIntra calculates inter- and intra-rater reliability coefficients.

Usage

relInterIntra(x, nrater=1, raterLabels=NULL, rho0inter=0.6,
               rho0intra=0.8, conf.level=.95)

Arguments

x

Data frame or matrix of rater by object scores

nrater

Number of raters

raterLabels

Labels for the raters or methods

rho0inter

Null hypothesis value for the inter-rater reliability coefficient

rho0intra

Null hypothesis value for the intra-rater reliability coefficient

conf.level

Confidence level for the one-sided confidence interval reported

Value

nil
