sonic uncertainties, the multidimensional case

Based on simulated but realistic data created to capture 5 distinct but related dimensions of variation, surveyed using adaptive testing principles (or CAT), whereby estimates are converged upon by a process of item selection contingent on prior responses, allowing sonification of 1000 peoples sets of scores.

The multidimensional cases are the person estimates converging on final score values, and the uncertainties are the conditional standard errors of measurement, reducing until sufficiently small.

Installation inspired by multidimensional IRT in personality and psychopathology data discussed with and prepared by Mark Fell, recreated in simulation scale and scope by Dr Jan Stochl and YCCSA student Alastair Scott, under direction from Tim Croudace
