`student(`

`t`, `nu` [, /complement])

Returns the value of the statistical Student’s t function at ordinate

for `t`

degrees of freedom, or one minus the
t function if `nu``/complement`

is specified.

If `r`

is the sample cross-correlation coefficient of `n`

value pairs drawn from a bivariate normal distribution, then its
distribution function is equal to ```
student(sqrt((n - 2)*r^2/(1 -
r^2)), n - 2)
```
