Designing measurement studies under budget constraints: controlling error of measurement and power.

A methodology is presented for minimizing the mean error variance-covariance component in studies with resource constraints. When designing measurement studies, two important statistical issues—power and measurement error—must be considered. Power is concerned with the number of observations to emp...
