延伸性的孿生設計之均方根期望值：投射法研究

Expected Mean Squares for Extended Twin Designs: A Projection Approach

本研究採用投射法探討延伸性的孿生設計均方根期望值之通用公式，顯示出其對行為基因學中變異成分模式背後假設之檢驗比目前普遍常用之卡方適合度檢定更為嚴格。

The projection approach is used to derive generic formulae for expected mean squares of extended twin designs. It is then shown how they can be used to obtain more stringent tests of the assumptions underlying variance component models used in behavior genetics than those afforded by global chi-square tests of fit in current use.
