利用重复观测估计多变量线性结构关系
SUMMARY We derive maximum likelihood estimators for parameters of a multivariate linear structural relationship in the replicated case. The asymptotic covariance matrix of the maximum likelihood estimator of the coefficient of the relationship is obtained by using the delta method when the sample size tends to infinity.
因子分析模型中的线性预测
For the problem of linear prediction in the factor analysis model, the heuristic predictor suggested by Scott (1966) and the unbiased predictor proposed by King (1969) are shown to be mathematically identical respectively with the optimal biased predictor and the optimal unbiased predictor due to Lawley & Maxwell (1973).
