A Computing Model for Marketable Quality and Profitability of Corporations: Model Evaluation Based on Two Different Sources Data

In this paper, we introduce and evaluate a computing model for marketable quality and profitability of corporations. We discuss the model prediction of the turning and transition periods based on data from two different sources. By applying these real data of some leading manufacturing corporations in Japan, we analyze the model accuracy. From the analysis, we conclude that even there are some differences between two sources data, the proposed model give a good approximation and prediction of the turning and transition periods of Japanese economy.
