ABX software with type II error statistics, beta version
http://ff123.net/export/abchr1.1beta.zip
This is a beta version (potentially buggy) of ABX software which pays more than just lip service to the analysis of type II errors. In the ABX module, critical values for type I and II error risks and effect size can be entered before starting a listening test. There is also a training mode so that effect size can be estimated. Presets are offered for identifying "obvious," "moderate," and "subtle" differences. These presets are geared towards the comparison of audio codecs, where false acceptance of "no difference" is not important (i.e., type II error risk is preset to a rather large 0.2), and also where a strict p-value is not needed nor even desirable. That is, the critical type I error risk is preset to 0.05, and not to something very strict like 0.002 (which is what 14 correct out of 16 would yield for a p-value). Feedback and bug reports are appreciated. Known bugs: 1. If ABX window is left open when new WAV files are loaded, the old status values are not cleared off. Additional features to be added before release: 1. More information to be written to the results file (i.e., the critical values for the error risks, the resulting type II error when a test is finished). 2. If an ABX is successfully completed (p-value 0.05) and a sample was being compared with the reference, the hidden reference in the ABC/hr window for that sample will be unhid. ff123 |
