Abstract
In a data-analyzing method in which an analysis based on a plurality of data groups each obtained by an instrumental analysis on each of a plurality of samples, with each data group including signal values having an n-dimensional array structure (where n≥2), is performed by using a computer, to obtain desired information concerning a difference between the samples, the method includes: a computational processing step for performing, in each data group, a persistent-homology processing on data including signal values having an m-dimensional array structure (where 2≤m≤n) obtained from one data group, to create a persistence diagram (PD); and an analytical processing step for comparing PDs respectively obtained from the data groups, to obtain the desired information based on a difference in the dispersion state of plots across the entire PDs being compared and/or based on information concerning a plot having no positional correspondence determined on the PDs being compared.
