%description
An alternative to Exploratory Factor Analysis (EFA) for metrical data in
R. Drawing on characteristics of classical test theory, Exploratory Likert
Scaling (ELiS) supports the user exploring multiple one-dimensional data
structures. In common research practice, however, EFA remains the go-to
method to uncover the (underlying) structure of a data set. Orthogonal
dimensions and the potential of overextraction are often accepted as side
effects. As described in Müller-Schneider (2001)
<doi:10.1515/zfsoz-2001-0404>), ELiS confronts these problems. As a
result, 'elisr' provides the platform to fully exploit the exploratory
potential of the multiple scaling approach itself.
