smaa.cf: SMAA confidence factors

In smaa: Stochastic Multi-Criteria Acceptability Analysis

SMAA confidence factors

Description

Calculate SMAA confidence factors of the central weights.

Usage

smaa.cf(meas, cw)

Arguments

meas	Criteria measurements. An N \times m \times n array, where meas[i,,] is a matrix where the m alternatives are the rows and the n criteria the columns. The values must be standardized measurements (i.e. after application of the partial value function).
cw	An m \times n matrix of central weights, where each row corresponds to an alternative and each column to a criterion.

Details

The confidence factor for an alternative is its first-rank acceptability under its central weight.

Value

An object of class smaa.cf, with the following elements:

cf	A vector of confidence factors, one for each alternative.
cw	The central weights (see smaa.cw).

The number of SMAA iterations is stored in attr(x, "smaa.N").

Examples

N <- 1E4; m <- 2; n <- 3
meas <- dget(system.file("extdata/thrombo-meas.txt.gz", package="smaa"))
pref <- dget(system.file("extdata/thrombo-weights-nopref.txt.gz", package="smaa"))

# Calculate central weights
values <- smaa.values(meas, pref)
ranks <- smaa.ranks(values)
cw <- smaa.cw(ranks, pref)
print(cw)
cf <- smaa.cf(meas, cw)
print(cf)
plot(cf)
