Sir
D Shattuck-Eidens and coworkers1 use logistic regression analysis to evaluate the probability that a breast cancer patient carries a deleterious BRCA1 mutation. Their formula takes up half a column of JAMA. The utility of such a model could not have been imagined a few years ago, before the age of pocket computers. Using the “sheet” function of a Psion 3C palmtop computer we have been able to bring this knowledge to the clinic immediately.

No. Logistic regression analysis utilizes a logistic function or logistic curve, a common sigmoid function, given its name (in reference to its S-shape) in 1844 or 1845 by Pierre François Verhulst who studied it in relation to population growth. A logistic curve has an equation of the form y = k/(1 + ea+bx), where b is less than zero.
