In quantitative research methodology, the empirical research method is finding importance due to its effectiveness in carrying out research in social sciences, business management, and health sciences. The empirical research method contains the procedure of developing a model to find the...

There are so many reasons of competition among products; the purpose of this study was to find different factors on which competition was dependent. Hypotheses were generated to find the impact of factors on competition. A cross-sectional design research study was conducts through a survey form...

The article employs a logistic regression model to predict defaults and optimize credit portfolios for enterprises receiving support, showcasing a rigorous methodological approach. It relies on empirical data to ensure the relevance of its findings and utilizes the Evidence-Based Policy Making...

This paper considers price volatility as the reason for description of the second-degree economic variables, trades and expectations aggregated during certain time interval Δ. We call it - the second-order economic theory. The n-th degree products of costs and volumes of trades, performed by...

We propose two tests for the equality of covariance matrices between two high-dimensional populations. One test is on the whole variance-covariance matrices, and the other is on offdiagonal sub-matrices which define the covariance between two non-overlapping segments of the high-dimensional...

We introduce the price probability measure η(p;t) that defines the mean price p(1;t), mean square price p(2;t), price volatility σp2(t) and all price n-th statistical moments p(n;t) as ratio of sums of n-th degree values C(n;t) and volumes U(n;t) of market trades aggregated during certain time...

This paper analyzes the effect of the recent market crash on the international diversification of equity portfolios from the perspective of dependence structure. We use the generalized Pareto distribution to fit the left and the right tail of each return distribution in order to evaluate the...

This paper models price volatility through description of the second-degree transactions and expectations averaged by time interval Δ. We call it - the second-order economic theory. First two price statistical moments define volatility. To model volatility one needs description of the squares...

This study examined the application of queue theory in the banking system in Democratic Republic of Congo, with particular reference to BCDC (Banque Commerciale du Congo)/Mbujimayi. The queuing characteristics of the bank were analyzed using a Multi-Server Queuing Model. The obvious implication...
