For any particular value of r, the Pearson product-moment correlation coefficient, this section will perform the Fisher r-to-z transformation according to the formula

If a value of N is entered (optional), it will also calculate the standard error of z_{r} as

z_{r} = (1/2)[log_{e}(1+r) - log_{e}(1-r)] |

SE_{zr} = 1/sqrt[N-3] |
