Web15 Jun 2024 · There are plenty of helpful built-in functions in R used for various purposes. Some of the most popular ones are: min (), max (), mean (), median () – return the … WebBy employing the cardinality of these basis functions, the nonlinear terms in the system under investigation are easily computed. This significantly reduces the difficulties and voluminous computational works. This approach does not need linearization, discretization and transformation techniques for obtaining a solution for the problem.
WebThe function is estimated from weighted penalized least square. ssr can be used to fit the general spline and smoothing spline ANOVA models (Wahba, 1990), generalized spline models (Wang, 1997) and correlated spline models (Wang, 1998). ssr can also fit partial spline model with addi-tional parametric terms specified in the formula (Wahba ...
