TAC Method for Fitting Exponential Autoregressive Models and Others: Applications in Economy and Finance
Javier Cabello Sánchez, Juan Antonio Fernández Torvisco, Mariano R. Arias
There are a couple of purposes in this paper: to study a problem of approximation with exponential functions and to show its relevance for the economic science. We present results…
Chebyshev approximation of exponential data
Mariano Rodríguez-Arias Fernández, Javier Cabello Sánchez, Juan Antonio Fernández Torvisco
In this paper we present an algorithm to fit data via exponentials when the error is measured using the max-norm. We prove the necesssary results to show that the algorithm will co…
A New Algorithm to Fit Exponential Decays
Juan Antonio Fernández Torvisco, Mariano Rodríguez-Arias Fernández, Javier Cabello Sánchez
This paper deals with some nonlinear problems which exponential and biexponential decays are involved in. A proof of the quasiconvexity of the error function in some of these probl…
