Application of Dissimilarity Measure of Concentration Ratios and its Critical Value to Heavy Metal contained in Bottom Sediment.

抄録

The authors (1981) proposed a dissimilarity measure for analyzing concentration-ratio data. Statistical distribution of this measure is derived when the original data are drawn from a p-dimensional lognormal distribution. This allows one to determine statistically whether two samples come from the same population. The result is applied to the data, according to KIBA and MATSUMOTO (1978), on bottom sediments of tributaries of the Jintsu River in Japan.
