qfsi: Q Methodology: Factor Stability index

Description

Calculates a Factor Stability index and a Normalised Factor Stability index to bootstrapped Q method results (experimental).

Usage

qfsi(nfactors, nstat, qscores, zsc_bn, qm)

Arguments

nfactors

number of factors to extract.

nstat

number of statements in the study.

qscores

all possible factor score values in the Q grid distribution.

zsc_bn

bootstrapped factor scores.

qm

original Q method results from qmethod function.
