回归模型的拟合效果分析一般情况下，使用估计的回归方程之前，需要对模型进行检验，其内容包括：（1）结合经济理论和经验分析回归系数的经济含义是否合理；（2）对模型进行假设检验。（3）分析估计的模型对数据的拟合效果如何（用决定系数来测度）决定系数，也称为R2，可以测度回归直线对样本数据的拟合程度。决定系数的...
What makes NPV unique compared to other projection formulas is that it considers the time value of money. This essentially mimics the concept of the declining purchasing power of money due to inflation. Say, an individual has a choice whether to cash out their insurance payout in a lump sum ...

Calculating the internal rate of return with pencil and paper can be complicated and time consuming. The NPV is calculated using estimated interest rates, so manually, you would need to use trial and error to determine the IRR. Luckily, there is a handy function available on Microsoft Excel an...
