DATA ANALYSIS PROGRAM, DATA ANALYSIS METHOD, AND DATA ANALYZER

摘要

PROBLEM TO BE SOLVED: To solve a problem that fitting of actual data to an objective variable tends to deteriorate in a multiple regression model.SOLUTION: There is provided a data analysis program for causing a computer to execute: a neighbor data extraction process of extracting neighbor data present around each sample data in a space configured by each of combinations of the explanatory variables for each combination of the explanatory variables per sample data while referring to an analysis database storing therein an objective variable table showing objective variables for each sample data and an explanatory variable table showing explanatory variables for each sample data; and a similar data extraction process of determining whether objective variable values of the neighbor data are higher in similarity than objective variable values of entire data, and extracting neighbor similar data and a similarity.
