处理黑色体系的几种化学计量学算法的比较

对近期提出的几种处理黑色分析体系的二维数据的算法－－渐进因子分析法，迭代目标转换因子分析法，演进因子分析法，直观推导式渐进因子分析法等４种算法进行比较研究，为了方便比较，以光谱或色谱的协方差阵的行列式作为体系重叠度的度量，在此基础上，对确定未知混合物组分数和纯组分光谱及色谱的分辨结果进行了较详细的讨论，ＨＥＬＰ给出最佳结果。

Comparison of Several Chemometric Methods for Analysing Black Analytical Systems

A comparison of several chemometric methods for analysing two-way data of black analytical systems is presented. The overlap in systems is judged by the determinant of the covariance matrix of the spectral or chromatographic vectors. Evolving Factor Analysis, Iterative Target Transformation Factor Analysis, EvolutionaryFactor Analysis and Heuristic Evolving Latent Projection (HELP) are compared in terms of determination of the number of components as well as spectral and chromatographic resolution by using simulated data. The HELP method gives the most satisfactory results.
