Correlation, in the finance and investment industries, is a statistic that measures the degree to which two securities move in relation to each other. Correlations are used in advancedportfolio management, computed as thecorrelation coefficient, which has a value that must fall between -1.0 and +...
A formula is proposed for calculating the correlation coefficient between the residuals together with a compact program created in the Maple V R5 mathematical... GA Ivanov,Yu. Y. Ponomarchuk,YR Chashkin - 《Measurement Techniques》 被引量: 0发表: 2002年 The Correlation of the Residuals in a...
If you know what is the current discount rate (also called the cost of capital or the interest rate), you can use that in the NPV formula in Excel to calculate the net present value of all the future inflows that you will have in the next 20 years with this investment. If that value...

The amount of evapotranspiration of farm land can be calculated by multiplying the largest possible evaporation capacity of water surface with a special coefficient.Therefore this method is also based on biology and physics and it takes many different factors into account.But, the formula is not ...
Due to the odds ratio formula, the value of one becomes critical during interpretation because it indicates both conditions have equal odds. Consequently, analysts always compare their OR results to one when interpreting the results. As the OR moves away from one in either direction, the associati...
4). The insignificance of the correction coefficient might result from the variation in the W/L ratio among the six species (Fig. 2d). There is a significant correlation between leaf area and W/L ratio among the six species (r = 0.84; P = 0.034 < 0.05), which means that with leaf ...
