Is it my understanding that the polygraph examiner himself determines how much variance in the chart readings in order to determine deception or no deception? I ask this based on the following lineini Mr. Hont's study regarding countermeasures:
"Followng the data collection, the examiner ran the CPS discriminant analysis classification software . . . . Participants who produced probabilities of trthfulness of .7 or greater were told they passed and were given the movie pass bonus."
So, what does this mean in layman's terms?
You cannot reasonably expect, in this forum, a primer on discriminate analysis, likelihood ratios or bayesian probabilities.
More succinct questions would be in order.
For basic information, of which there is sometimes a lot, you can refer to any advanced statistics texts or treatises. However, many find it easier to learn about statistics in a classroom with other students vs. self study.

Thank-you Mr. Nelson for your comments. Based on your response, I guess there is no way to discuss this in laymans terms.
