1 * This program does (as backprop always does) a form of non-linear
\r
2 * regression. The goal is to predict the reactivity of certain chemical
\r
3 * compounds given data about those compounds. This particular data
\r
4 * comes from "1-(Substituted-benzyl) imidazone-2(3H)-thione Inhibitors
\r
5 * of Dopamine B-Hydroxylase", by Benjamin J. Burke and A. J. Hopfinger
\r
6 * in the Journal of Medicinal Chemistry 1990, volume 33, pages 274-281.
\r
7 * Oh, yes, QSAR stands for Quantitative Structure Activity Relationship.
\r
9 * There are two data sets you can use. The one in qsar.dat is the
\r
10 * original form of the data. The one in qsar2.dat has been modified
\r
11 * so that the fifth input parameter has been divided by 10. I haven't
\r
12 * done a complete investigation of both sets but the second one may
\r
13 * work a little better.
