Abstract
The reproducibility of multivariate measurements is discussed. Reproducibility of a second kind is defined, in which part of the variability between samples is described by a principal components model. The use of this generalized reproducibility is shown to give an improved precision in the pyrolysis-gas chromatography of a Penicillium species.
摘要
讨论了多变量测量的可重复性。定义了第二类可重复性，其中样本间的部分变异性由主成分模型描述。结果表明，使用这种广义可重复性可提高青霉菌种热解气相色谱分析的精度。
