In this paper we present the Radial Basis Neural Network Function. We examine some simple numerical examples of time-series in economics and finance. The forecasting performance is significant superior, especially in financial time-series, to traditional econometric modeling indicating that...

In this paper discrete choice models, Logit and Probit are examined in order to predict the economic recession or expansion periods in USA. Additionally we propose an adaptive neurofuzzy inference system with triangular and Gaussian membership functions and genetic algorithms training...

In this paper we present a very brief description of least mean square algorithm with applications in time-series analysis of economic and financial time series. We present some numerical applications; forecasts for the Gross Domestic Product growth rate of UK and Italy, forecasts for S&P 500...

In this paper we present, propose and examine additional membership functions. There is no reason why more functions cannot be proposed. More specifically, we present the tangent hyperbolic, Gaussian and Generalized bell functions. Because Smoothing Transition Autoregressive (STAR) models follow...

In this paper we examine feed-forward neural networks using genetic algorithms in the training process instead of error backpropagation algorithm. Additionally real encoding is preferred to binary encoding as it is more appropriate to find the optimum weights. We use learning and momentum rates...

This paper examines the efficiency of decision trees on US economic crisis periods. Many other studies examined various approaches, like noise-to-ratio models, discrete choice models, neural networks, fuzzy logic and neuro-fuzzy systems among others. Two approaches are applied. The first is a...

The purpose of the paper is to test empirically the existence of the environmental Kuznets curve (EKC), using existing and new Panel Smoothing Transition Regressions (PSTR) in the city of London. More specifically, two new PSTR are proposed, the Gaussian and the Generalized Bell function used...

In this paper we provide MATLAB routines for two major used trading rules, the moving average indicator and MACD oscillator as also the GARCH univariate regression with Monte Carlo simulations and wavelets decomposition, which is an update of an older algorithm

In this paper we provide a simple MATLAB routine which computes the moving median with trend and seasonality. This approach is linear and for this reason has its disadvantages. So this routine can be improved by combining Monte-Carlo simulations, genetic algorithms simulations and wavelets...

This paper examines the consumers' preferences to the local furniture market in the Province of Serres. We apply a multinomial logit model to investigate the probability of buying a furniture in the following four-monthly period. We analyze also the demographic characteristics and we conclude...
