Abstract: A method and an apparatus for outputting information are provided. The method includes: acquiring at least one piece of test data generated in a target period; performing a fitting calculation on the at least one piece of test data to obtain estimated test data in the target period; and determining, for a test time point in the target period, a difference value between test data generated at the test time point and corresponding estimated test data as a target difference value; determining at least one historical correspondence difference value corresponding to the determined target difference value; and generating and outputting a data fluctuation value based on the determined target difference value and the determined at least one historical correspondence difference value.
