Original Abstract

The regression model for a two-segments titration curve with a break-point at the end-point is analyzed. Both linear and nonlinear shapes of the titration curve segments are treated. An effective and simple method discriminates which of two segments is linear or curved. The point and interval estimates of the end-point are calculated by the nonlinear least squares of curve fitting technique.
