A flexible nonparametric regression model is considered in which the response depends linearly on some covariates, with regression coefficients as additive functions of other covariates. Polynomial ...

We propose a global smoothing method based on polynomial splines for the estimation of functional coefficient regression models for non-linear time series. Consistency and rate of convergence results ...

Horadam Polynomials: A generalised family of polynomials which includes classical sequences such as Fibonacci and Lucas polynomials, utilised in deriving coefficient estimates.

Research from Nature Portfolio A recent investigation has utilised Horadam polynomials to establish initial coefficient bounds and derive the corresponding Fekete–Szegö inequalities. This study ...
