Analysis System and Method for Time of Change Point of Spontaneous Vaccine Adverse Event Reports

摘要

The present invention relates to a temporal variation point analysis system and analysis method of spontaneous vaccine adverse event report, and according to the present invention, a database unit for storing spontaneous adverse event report data; A data preprocessing unit that pre-processes the target vaccine-adverse event report data from the voluntary adverse event report data; and a variation point analysis unit that tests for the significance of temporal variations in the distribution of the cumulative sum width of the index deviations of multiple samples, so as to statistically search or A technique capable of analysis is disclosed.
