DATA ANALYSIS APPARATUS, DATA ANALYSIS METHOD, AND DATA ANALYSIS PROGRAM

To implement a highly accurate prediction analysis that does not depend on data amount. A data analysis apparatus has a processor that is configured to execute: an acquisition processing of acquiring a first statistical model based on a distribution of actual measurement results of a group and a second statistical model based on a distribution of a first actual measurement result of first samples having a smaller number of samples than the number of samples of the group; a calculation processing of calculating correction information indicating a difference between the first statistical model and the second statistical model; a learning processing of generating a first prediction model by performing machine learning using the first actual measurement result and first feature amount data corresponding to the first actual measurement result; and a correction processing of correcting a first prediction result , and outputting a second prediction result.
