A method for evaluating the validity of multicomponent measurement instruments in heterogeneous populations is discussed. The procedure can be used for point and interval estimation of criterion validity of linear composites in populations representing mixtures of an unknown number of latent classes. The approach permits also the evaluation of between-class validity differences as well as within-class validity coefficients. The method can similarly be used with known class membership when distinct populations are investigated, their number is known beforehand and membership in them is observed for the studied subjects, as well as in settings where only the number of latent classes is known. The discussed procedure is illustrated with numerical data.
本文讨论了一种评估异质群体中多组分测量工具有效性的方法。该程序可用于对代表未知数量潜在类混合的群体中线性合成物的标准有效性进行点估计和区间估计。该方法还允许评估类间有效性差异以及类内有效性系数。当研究不同群体时，如果预先知道其数量并且观察到研究对象在这些群体中的成员身份，以及在仅知道潜在类数量的情况下，该方法同样可以用于已知类成员身份的情况。文中用数值数据说明了所讨论的程序。
