Pearson Test R. R s statistics base package implements the test cor test x y method pearson in its stats package also cor x y method pearson will work but without returning the p value. They are calling functions from r s contributed package nortest.
They are calling functions from r s contributed package nortest. Pearson correlation coefficient or pearson s correlation coefficient or pearson s r is defined in statistics as the measurement of the strength of the relationship between two variables and their association with each other. It can be used only when x and y are from normal distribution.
It s also known as a parametric correlation test because it depends to the distribution of the data.
The remaining five normal tests are the anderson darling test the cramer von mises test the lilliefors kolmogorov smirnov test the pearson chi square test and the shapiro francia test. Then pearson s chi squared test is performed of the null hypothesis that the joint distribution of the cell counts in a 2 dimensional contingency table is the product of the row and column marginals.
