从预测中国夏季降水趋势分布的需要出发 ,定义了一个反映北太平洋海域表面温度变化的分布型指数。该指数较好地表征出海温的年际变化特征及厄尔尼诺和拉尼娜事件 ,及其与中国夏季降水分布型式有较清晰的相关关系。在分析分布型指数变化... 从预测中国夏季降水趋势分布的需要出发 ,定义了一个反映北太平洋海域表面温度变化的分布型指数。该指数较好地表征出海温的年际变化特征及厄尔尼诺和拉尼娜事件 ,及其与中国夏季降水分布型式有较清晰的相关关系。在分析分布型指数变化特征基础上构建了一个统计预测模式。模拟计算及 3 6个个例提前 6个月的预测试验结果表明 ,该模式可以较好地预测出北太平洋海温的变化趋势 。 展开更多

The main goal of this research is to enhance the auditor's judgment ability in going concern opinion by applying bankruptcy prediction models as an analytical procedure. Data for this research have been collected through questionnaires. The statistical population consists of auditors who are members of Iranian Association of Certified Public Accountants (IACPA). The research results reflect that: (1) Auditors do not use statistical techniques for assessing going concern as an analytical procedure; (2) Auditors do not use these techniques as a tool to decrease the bias of judgments in assessing the going concern assumption; (3) Auditors do not use statistical techniques to assess audit risk in the planning stage; (4) Auditors do not use statistical techniques to assess audit risk in the final stage. Furthermore this research shows that auditors believe that the "standard concerning usage of analytical procedures needs more clarification" and "statistical bankruptcy predication models can help auditors in the planning stage". The other goal of this research is to show different auditor's judgments in assessing the going concern opinion with and without applying the bankruptcy prediction models as an analytical procedure. The result shows that the judgment of auditors toward the going concern assumption has improved by using statistical bankruptcy predication models. 展开更多
