Both financial and non-financial data were collected from a sample of petrochemical companies for the period march, 1998 through March 2001. The information was used to predict sales revenue and production expense account balances. According to the results, regression models have better performance for predicting account balances in performing auditing analytical procedures in comparison to Two other models. Logarithmic regression has been evaluated as the best statistical analytical procedure. The foresaid procedure has a constant performance in sample companies of the industry.
