Neuralgia Data

Neuralgia is pain that follows the path of specific nerves. Neuralgia is most common in elderly persons, but it can occur at any age. The Neuralgia data set contains data on 60 patients. These data are hypothetical, but they are similar to data reported by Layman, Agyras, and Glynn (1986).

Two test treatments and a placebo are compared. The response variable is Pain, which has the value "No" if the patient reports no pain or a substantial lessening of pain, and the value "Yes" if the patient still experienced pain after treatment.

The explanatory variables are as follows:


treatment administered. "A" and "B" represent the two test treatments. "P" represents the placebo treatment.


gender of the patient


age of the patient, in years, when treatment began


duration of complaint, in months, before the treatment began
