A Note on the Linear Structural Relation When Both Residual Variances are Known
两个残差方差均已知时线性结构关系的一则注记
This article provides an alternative derivation of a maximum likelihood solution, due to Birch [1], which simplifies the algebra and characterizes Birch's solution as a special case of a result, due to Dolby [2], that has application to a variety of more complex structural models, including factor analysis.
