A note on the statistical power in extended twin designs.

Behavior genetics - 1 Mar 2000

Posthuma D, Boomsma D I

Abstract excerpt

The power to detect sources of genetic and environmental variance varies with sample size, study design, effect size and the statistical significance level chosen. We explored whether the power of the classical twin study may be increased by adding non-twin siblings to the classical twin design. Sample sizes to detect genetic and shared environmental variation were compared for kinships with only twins, kinships...
