対数比法における規格化成分選定プログラム―Woronow-Love-Schedl法の自動化―

The Woronow-Love-Schedl method is a logratio-based statistical assessment for detecting immobile variables in compositional data. The method was designed in order to address the constant-sum constraint. This method is effective, but difficult to apply without special statistical software. A computer program to process the method for open source statistical environment ‘R’ was developed. This program enables a user to assess the immobile variables in given data set. Care must be taken, however, because the program just gives some statistical information about the candidates for immobile variables. Hence, additional geological evidence is necessary for a definite decision about immobility.
