In this study, the simultaneous determination of Co, Cd, Ni, Cu, and Pb was carried out as a color complex with 4-(2-pyridylazo) resorcinol in an aqueous solution under the assesting of machine learning. A partial least-squares multivariate linear regression and artificial neuron network for the analysis of mixtures of metals were developed. MATLAB is a powerful software machine learning program that was used to support matrix calculations and displays.

The official study sample includes 89 industrial group of companies listed on HOSE with a sample size of 267 observations between 2018 and 2020. The panel data regression methods POOL, FEM, REM, and FGLS are used to validate the research model. The study result provides further empirical evidence on the quality of financial reports of industrial group of companies that are negatively influenced by the age of the CEOs. The result also recommends that industrial group of companies should not recruit or appoint CEOs who are too old to increase the quality of financial reports.
