unit sample

Specifically, the cluster randomised designs introduce dependence (or clustering) between individual units sampled.

To finish the calculation for DOS find the number of states per unit sample volume at an energy inside an interval .

Sample (Monetary unit): Specifies whether the product supports selecting a monetary unit sample of rows from the table/field (population).

"D"( "n" - 1 ) is distributed as the chi squared variable with "n" - 1 degrees of freedom where "n" is the number of units sampled.

However, if clusters are selected with probability proportionate to size, the same number of interviews should be carried out in each sampled cluster so that each unit sampled has the same probability of selection.
