Structural equation modeling (SEM) employing the partial least squares (PLS)
method, or PLS-basedSEM for short, has been and continue being extensively used in
a wide variety of fields.
Examples of fields in which PLS-basedSEM is used are information systems
(Guo et al., 2011; Kock & Lynn, 2012), marketing (Biong & Ulvnes, 2011),
international business (Ketkar et al., 2012), nursing (Kim et al., 2012), medicine
(Berglund et al., 2012), and global environmental change (Brewer et al., 2012).

The software installs automatically from a self-extracting executable file.
There are two components to the software: the MATLAB Compiler Runtime, and the
main software (i.e., WarpPLS).
The MATLAB Compiler Runtime 7.14 is used in this version of WarpPLS.

This version was initially released as a beta version and was later
upgraded to stable. As you will see below, it incorporates a large number of new
features, when compared with the previous version. It has undergone extensive testing
in-house prior to its release as a beta version, and has been in the hands of users for
several months prior to its upgrade to stable. Nevertheless, given the large number of
new features, and the inherent interconnectedness of features, it is very likely that
this stable version will still contain some software bugs, which we expect to be
minor.

Prior to displaying the software’s main window, a command prompt
window may be shown and kept open for the duration of the SEM analysis
session. Do not try to close this command prompt window, if it is shown, because it
will list warnings and error messages that will likely be very useful in troubleshooting.
Moreover, those warnings and error messageswill indicate where in the source code
they are happening, which will help the software developer correct any possible
problems in future versions of the software.
