The Naturalistic University of Alberta Nonlinear Correlation Explorer
(NUANCE) is a tool
that allows you to harness the power of evolution in your
attempts to explore intricacies within your data. The
of psychology typically dictate that we treat variables
categorically during analysis (e.g. high/low event frequency,
regular/irregular word spelling). However, many of the
use to study psychological phenomena are continuous, and our
treatment of them as categorical indicators can gloss over
of the finer grained details of what is going on. NUANCE
you to build mathematical representations of your variable
relations, defined across each variable's entire range. However,
unlike most regression techniques
in common use, NUANCE's ability to provide suitable fits does
require you to have prior knowledge of either the proper
transformations that need be applied to the data, or of the
of the curve relating your predictor to your dependent
NUANCE is the computational embodiment of selective breeding:
with a pressure towards minimizing error, NUANCE manages
thousands of mathematical formulae that describe your data,
selecting those that fit it best and recombining them in random ways
to generate new formulae. Through this iterative process,
will show you ways to look at your data you would have never
imagined, and highlights important relationships you would
never assumed existed!
