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.

In order to evaluate consistency and dependency of measured and simulated data, sample correlation coefficient (r) is determined as follows:
2) Sample correlation coefficient (r) between measured and simulated energy is around 0.
where r is the sample correlation coefficient between R and I.
From (7) and (9), it is observed that the covariance matrices V([absolute value of S]) and V([phi]) rely on the sample correlation coefficient r between R and I.
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,
Generally, the measurement error arises on account of the lack of construct validity and attenuates the magnitude of a sample correlation coefficient.
Again, this result is consistent with the increased variability of the sample correlation coefficient for small sample sizes.
A sample correlation coefficient of 1 means the parameters are directly correlated and a coefficient of -1 indicates an inverse relationship.
1) Pearson's sample correlation coefficient, let's denote it by [r.
Odeh [60] tabulated, to 5D, quantiles x of the sample correlation coefficient, where F(x) = p for p = 0.
The positive correlation between X and Y is measured by the sample correlation coefficient (r).
This study examined bias in the sample correlation coefficient, r, and its correction by unbiased estimators.
