1. A data analysis apparatus comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
acquire a pair data of a first data indicating a characteristic of a specific region and a second data corresponding to the first data and indicating another characteristic of the specific region, and aligns the first data in order of their sizes,
perform grouping a data set of the pair data based on a characteristic of an order distribution of the first data after alignment, classify the data set of the pair data into a plurality of groups, and generate a classification model for classifying the pair data using the classification result,
perform machine learning for each group, using the first data constituting the pair data as a response variable and the second data constituting the same pair data as an explanatory variable, and generate a regression model indicating a relation with the first data and the second data.
