The second author and \textit{W. Hess} [Positive interpolation with rational quadratic splines, Computing 38, 261-267 (1987)] have given a necessary and sufficient condition according to which the property of positivity carries from the data set to rational quadratic spline interpolants of a special form. In the present paper positive rational splines of continuity class \(C^ 2\) are constructed by a method situated between a cubic spline method and a piecewise linear one. The Schmidt-Hess method appears as a limiting case.
