Fisher studied the correlation of bivariate normal data and discovered a wonderful transformation (shown to the right) that converts the skewed distribution of the sample correlation ( r) into a distribution that is approximately normal. Furthermore, whereas the variance of the sampling distribution of r depends on the ...

WebThis extension, and thus these options in SAS and R, of the Fisher's exact test for a \(2 \times 2\) table, in effect, takes samples from a large number of possibilities in order to simulate the exact test. This test is "exact" because no large-sample approximations are used. The \(p\)-value is valid regardless of the sample size. WebFisher's exact test is recommended in those cases, but I haven't been able to do this in R so far. If I try it on the whole table, I get FEXACT errors, complaining either that LDKEY or LDSTP are too big or too small. It does not allow me to take just one column, as it needs a table structure of at least 2x2. It allows me to test two columns at ...
