Full Description

The within-implicate variance for a generic variable `X` is:

`V^{(l)}[\hat{X}_{agkt}] =\ 1/49 sum_{AAs}\frac{(\frac{F_{agkst}^{(l)}+F_{agkst-1}^{(l)}}{2})(X_{agkst}^{(l)}-\hat{X}_{agkt}^{(l)})^2}{sum_{AAv}(\frac{F_{agkvt}^{(l)}+F_{agkvt-1}^{(l)}}{2})}`

where `1/49` is the number of states minus 1.
