| contents | This study revisits regression for samples with alternating predictors (SWAP) proposed in Chow et al.[2015] with the purpose of finding the best fit model when the role of the response and the explanatory variables was established. In the current work, we explore the directional relationship between the two variables at a given point of time, by a novel approach which draws direct inspiration from the concept of SWAP regression. Our method, based on the Gaussian Mixture Model (GMM) and the beta distribution, while estimating the probability of a latent variable, predicts the suitable model, i.e., earmarks if a variable can take the role of an explanatory or response, at any point of time. To make this switch-over role between variables, a valid consideration, we have established the existence of a bi-directional (Granger) causality between the two variables. A detailed real data analysis of the methodology is carried out using the historical quarterly data on probably the two most intertwined macroeconomic indicators explaining the health of an economy, viz., the Gross Domestic Product (GDP) and Public Debt, thereby making the application, in real data, more challenging. In particular, we use data of the US economy during the sample period 1966-2023. |
