Comparison of TSCS regression and neural network models for panel data forecasting: debt policy

Abstract

Empirical studies of variations in debt ratios across firms have analyzed important determinants of capital structure using statistical models. Researchers, however, rarely employ nonlinear models to examine the determinants and make little effort to identify a superior prediction model among competing ones. This paper reviews the time-series cross-sectional (TSCS) regression and the predictive abilities of neural network (NN) utilizing panel data concerning debt ratio of high-tech industries in Taiwan. We built models with these two methods using the same set of measurements as determinants of debt ratio and compared the forecasting performance of five models, namely, three TSCS regression models and two NN models. Models built with neural network obtained the lowest mean square error and mean absolute error. These results reveal that the relationships between debt ratio and determinants are nonlinear and that NNs are more competent in modeling and forecasting the test panel data. We conclude that NN models can be used to solve panel data analysis and forecasting problems.

Unified knowledge based economy hybrid forecasting

“…A unique study by Pao and Chih [22] concluded that ANN models can be used to solve panel data regression, and that would allow us to construct and test sophisticated models than purely cross-sectional or time-series data to solve debt policy forecasting problems.…”

Using deep learning neural networks to predict the knowledge economy index for developing and emerging economies

“…One of the first works in the literature to use of neural networks for the prediction of economic data was Pao (2006) who concluded that neural networks had a capability equivalent or superior to that of traditional regression techniques for the prediction of time series in economics. In (Kuhlman, 2017) a group lasso predictive model was trained to generate an index developed by the authors themselves that aims to measure the level of innovation in each country.…”

Sequential modeling of a low noise amplifier with neural networks and active learning

“…This has resulted in applications in many domains, including chemistry [1], economics [17] and hydrology [3]. ANNs have also seen successful use in electro-magnetism and microwave applications.…”
