laWRBM {iMRMC}

MRMC analysis of within-reader between-modality limits of agreement

Description

The core analysis is done by ustat11 with the difference kernel (kernelFlag = 2). This calculation can also be accomplished by ustat11 with the identity kernel (kernelFlag = 1), and the code to do that is provided after the return statement so it never gets executed.

Usage

laWRBM(
  df,
  modalitiesToCompare,
  keyColumns = c("readerID", "caseID", "modalityID", "score")
)

Arguments

df

an iMRMC formatted data frame, see dfMRMC_example

modalitiesToCompare

The factors identifying the modalities to compare.

keyColumns

Identify the factors corresponding to the readerID, caseID, modalityID, and score (or alternative random and fixed effects).
