Use of eviews5 software, cointegration test, error correction and measurement methods used to determine the various elements of the correlation coefficient to obtain the best fit between the various elements, that is, to find the elements of the proportion of investment, and thus clear the directi...
B. −0.75 and the two variables are negatively associated.C. −1.33 and the two variables are negatively associated. 正确答案:B 分享到: 答案解析: The correlation coefficient is the covariance divided by the product of the two standard deviations, i.e. −0.003 / (0.08 × 0.05). 统计...
The three models had correlation coefficients (R 2 s) of 0.81, 0.74 and 0.69, respectively. Perhaps the most unexpected result was that the age of the condom lot was the best predictor of condom breakage during use (correlation coefficient (R 2 ) = 0.92). Although the present investigation...
The linear correlationcoefficientmeasures the relationship between the paired values in a sample.( r=(n(( ∑ _(^(xy)-( ∑ _(^(x( ∑ _(^y/(√(n(( ∑ _(^(x^2)-((( ∑ _(^(x))^2)⋅ √(n(( ∑ _(^(y^2)-((( ∑ _(^()y))^2)))Sum up the values of the first...
