Results: 6 of the 8 models present high degrees of prediction, performance and level of adjustment, demonstrating statistical soundness of the ROA and ROE indices for the financial performance of microenterprises, segmented by sector and size, defining the impact of long-term debt, working capital, current amount, DuPont and acid index on profitability.
