Hi Helmut,

❝ The CVs calculated from the confidence intervals in both ‘parts’ are much lower than the ones in the ‘full’ study. Or the other way ’round: If we pool the CVs of the ‘parts’ we could expect values which are lower than the ‘observed’ (tee-hee!) ones.

Yep. The effect on the MSE is clearly visible on Figure 4 of the paper linked by ElMaestro.
