Used multivariate procedures to determine whether psychiatric patients who had made a suicide attempt immediately prior to hospitalization (N = 161) could be differentiated from nonsuicidal psychiatric patients (N = 161). Multivariate analysis of variance and cluster analysis failed to identify differences in the MMPI data of suicidal and nonsuicidal patients. In contrast, discriminant analysis produced a modest degree of differentiation that generally was maintained in the cross-validation.
使用多变量程序来确定在住院前立即有过自杀企图的精神科患者（N = 161）是否能够与非自杀性精神科患者（N = 161）区分开来。方差的多变量分析和聚类分析未能识别出自杀性和非自杀性患者在明尼苏达多相人格调查表（MMPI）数据上的差异。相比之下，判别分析产生了一定程度的区分，这种区分在交叉验证中总体上得以保持。
