Factor analysis device, factor analysis method and program, and factor analysis system

摘要

Provide a technology that can clarify the change of the variable of the objective variable. The factor analysis device includes: an acquisition unit that acquires time series data of an objective variable representing an event result from the factor analysis data; time series data of an explanatory variable representing an event factor; A reference value setting unit for setting a plurality of objective variable reference values; and learning the time-series data of the set plurality of objective variable reference values and the acquired explanatory variables; and for each objective variable reference value , An influence calculation unit that generates a relational expression between the objective variable reference value and the explanatory variable, and extracts a coefficient of the explanatory variable and the explanatory variable corresponding to the coefficient from the generated relational expression And an output unit that outputs the extracted coefficient as an influence level, and further outputs an explanatory variable name related to the extracted explanatory variable.
