The present invention provides that the analysis can be estimated the characteristics of the originated populations which belong to the samples and the characteristics of the samples from sample data. By loading the sample data, by interfering with the second state variable showing the characteristics in the environment system to the first state variable showing the characteristics in the objective system, by converging the variable by selecting the maximum resonant state, and by estimating the characteristics of the samples and the characteristics of the originated populations which belong to the samples, then the result estimated the characteristics of the originated populations is outputted.
