EFFECT statement. A spline function is a piecewise polynomial function in which the individual polynomials have the same degree and connect smoothly at join points whose abscissa values, referred to as knots, are prespecified. You can use spline functions to fit curves to a wide variety of data...
The cubic Hyperbolic B-spline has produced much better errors than the Quartic Hyperbolic B-spline. The statistical validation of the parameters is also provided via generating the correlation matrix heatmap.doi:10.1007/s10910-024-01652-2Mamta Kapoor...
