An unbiased estimator and a Sequential Probability Ratio Test (SPRT) for the correlation coefficient are proposed. The SPRT reduces to the SPRT for a binomial parameter. A comparison is made of the proposed test with those of Kowalski [4] and Choi [1].doi:10.1080/01621459.1975.10480278...

To decrease the variance of the estimate of I, importance sampling is often used to recast the problem as (5.101)I=∫Vg(x)f⁎(x)f⁎(x)dx, where f⁎(x) is a PDF that is approximately proportional to g(x). An unbiased estimator of I is the straightforward sample-mean estimator...
