sample correlation coefficient

sample correlation coefficient

[¦sam·pəl ‚kä·rə′lā·shən ‚kō·ə‚fish·ənt]
(statistics)
The ratio of the sample covariance of x and y to the standard deviation of x times the standard deviation of y. Also known as product-moment coefficient.

Sample Correlation Coefficient. We have generated N observations of correlated Nakagami-lognormal RVs following the methods described above.
In order to evaluate consistency and dependency of measured and simulated data, sample correlation coefficient (r) is determined as follows:
r = Sample correlation coefficient [C.sub.v](RMSE) = Coefficient of variation of the root-mean-square error n = Sample size Subscripts s = simulation variable m = measured variable i = index REFERENCES
where r is the sample correlation coefficient between R and I.
A 2 x 2 variance-covariance matrix [V.sub.rec] is used to describe the complex-valued variable S in terms of its standard uncertainties u(R) and u(I) for R and I and the sample correlation coefficient r between R and I in a rectangular coordinate,
Possibly these disparities resulted from variability of the sample correlation coefficient for small N.
R([y.sub.1],[y.sub.2]) = the sample correlation coefficient between variable [y.sub.1] and [y.sub.2];
