✦ Synopsis

A method of data int.eqxetation known as nonlinear least squares has recently been applied by several anthors to the study of polymeric materials. Nagler has used a modified method proposed by Blizzard and Jirka and has concluded that the method is impractical because it requires excessive computer time. It is shown that the difficulties Nagler encountered are inherent in Blizzard and Jirka's method, biit not in the basic method. Three steps are outlined to minimize computer time, and a summary of successful applications is presented.

Data from 14 patients with benign intracranial hypertension (pseudotumor cerebri) have been analyzed using a nonlinear least-squares regression model which was developed and programmed for in-hospital microcomputer use. The method of analysis permits rapid estimation of cerebrospinal fluid (CSF) for
