TIR: Total-Intra Ratio (TIR)

In Agreement: Statistical Tools for Measuring Agreement

Description

Total-Intra Ratio (TIR) is the ratio of MSD(total) and MSD(intra), it compares the total-rater agreement to intra-rater precision.

Usage

TIR(data, k, m, testindex, refindex, error, alpha = 0.05)

Arguments

data	Name of your dataset.
k	Number of methods/raters/instruments/assay, etc.
m	Number of replications for each methods/raters/instruments/assay, etc.
testindex	The index for the test raters, it can be a numerical vector or a character value "all". For example, if testindex=c(1,2), the first and second rater are selected as the test raters for calculating TIR.
refindex	The index for the reference raters, it can be a numerical vector or a character value "all". For example, if refindex="all", all raters are selected as the reference raters for calculating TIR.
error	error="const" for the constant error structure for continuous data. error="prop" for the proportional error structure for continuous data. Here, log transformation to data will be applied for the continuous data. For categorical data, use error="const".
alpha	100(1-alpha)

Value

Return a list of values

TIR	The estimator of TIR.
TIR_upper	The upper 1-alpha confidence limit for TIR.
TIR_lower	The lower 1-alpha confidence limit for TIR.
