摘要
本文提出了有关混凝土强度数据回归分析的几个应注意的问题。通过实例说明应选择合适的方程进行回归,提出回归方程具有不要可逆性和不可随意变换的性质。若统计概念不清,有时会造成不应有的失误。本文所得的几点结论对混凝土强度数据的处理及其它统计分析的研究工作有一定的参考价值。
The paper presents some points for attention in regression analysis of concrete strength data. The author holds, by presenting a case history in this paper, that an adequate equation should be derived for regression analysis, which, he points out, should be irreversible and should not be arbitrarily convertible. If the statistical concept is not clear, unjustable errors may be committed in the analysis. The conclusions given in this paper may provide some guidelines for the processing of concrete strength data and other statistical analyses.
