摘要

Conventionally, a signal analysis apparatus, a signal analysis method, a computer program, a measuring apparatus and a measuring method for performing cluster analysis so as to enable acquisition of a distribution which is difficult to obtain from a spectral distribution are provided.The signal analysis apparatus generates an n-dimensional coordinate point defined by the combination of the intensity of N specific signals contained in the spectrum for each point in the spectral distribution, defines an initial value of a plurality of clusters on the n-dimensional space to classify multiple n-dimensional coordinate points, and uses the initial initial value Cluster analysis is performed.The signal analysis apparatus generates an initial value of the cluster containing points on the n-dimensional space which is a combination of the representative values of the intensity of N specific signals in determining the initial value of the cluster, and generates an initial value of the cluster containing the n-dimensional coordinate points whose intensity of the specified signal is out of the predetermined reference .
