Full Description
The total variation for a generic variable `X` is:
`T[\bar{X}_{agkt}] =\ 1/M sum_{l=1}^{M}V^{(l)}[\hat{X}_{agkt}] + (M+1)/M B[\bar{X}_{agkt}]`
where `V^{(l)}[\hat{X}_{agkt}]` and `B[\bar{X}_{agkt}]` are respectively the within implicate variance and the between implicate variance of `X`.
