1. A parameter-setting method to obtain a parameter value with which an observed value or an index value derived from the observed value satisfies a predetermined condition in a target chromatograph and/or spectrometer system which outputs the observed value by performing an observation under a given parameter value, the target chromatograph and/or spectrometer system being a physical or chemical analysis system configured to perform a predetermined type of physical or chemical analysis of samples, and to set the parameter value in the target chromatograph and/or spectrometer system, the parameter-setting method comprising:
a model estimation step to estimate a posterior distribution of a model function of the target chromatograph and/or spectrometer system based on target observation data observed with the target chromatograph and/or spectrometer system and reference observation data observed with a reference system related to the target chromatograph and/or spectrometer system, the model estimation step including a variation estimation step to estimate an amount of variation between the target observation data and the reference observation data within a parameter space based on the two kinds of observation data, and the model estimation step further estimates a posterior distribution of the model function after a correction corresponding to the estimated amount of variation is made;
a parameter determination step to determine a parameter value which is a condition for a subsequent observation, based on the posterior distribution of the model function acquired through the model estimation step;
a data acquisition step to set the determined parameter value in the target chromatograph and/or spectrometer system, and acquire additional target observation data from the target chromatograph and/or spectrometer system by performing the predetermined type of physical or chemical analysis of a sample while the determined parameter value is set in the target chromatograph and/or spectrometer system;
repeating a process of the model estimation step, the parameter determination step and the data acquisition step to update the determined parameter value;
setting an updated determined parameter value in the target chromatograph and/or spectrometer system as an optimal parameter value of the target chromatograph and/or spectrometer system; and
performing a measurement with the target chromatograph and/or spectrometer system with the updated determined parameter value set in the target chromatograph and/or spectrometer system.
