The method of collecting information was based on two library models and the information included in the financial statements of the companies. To estimate the value relevance of accounting information in this study, the non-parametric method of classification and regression tree (CART) was used, which automatically includes non-linear relationships and interactions between variables, and simple linear regression was used to test the trend of value relevance.
