For normally distributed data, the distribution of the sample correlation was obtained in 1915 by R. A. Fisher. The test statistic N−2r/1−r2 can be used to test that the population correlation is zero; under
[___] = crosscorr(___,Name=Value)uses additional options specified by one or more name-value arguments. For example,crosscorr(Tbl,DataVariables=["RGDP" "CPI"],NumLags=10,NumSTD=1.96)returns the sample XCF for lags -10 through 10 of the table variables"RGDP"and"CPI"inTbland 95% confid...

We can test for sample selection formally by using, for example, Bayes factors. A Bayes factor of two models is simply the ratio of their marginal likelihoods. The larger the value of the marginal likelihood, the better the model fits the data. To test for sample selection, we can compare...
