Abstract: An anomaly of a moving object is detected by using a regression function according to k-nearest-neighbor crossover kernel regression. The regression function is configured to derive an estimation value for a value of a second item from a value of a first item regarding a movement of the moving object. Whether the moving object has an anomaly or not is determined, based on whether a difference between an estimation value of the second item and an actually measured value of the second item is smaller than or equal to a threshold. The estimation value of the second item is derived by the regression function from a value of the first item in the log data having values of the first item and values of the second item, and the actually measured value of the second item is also included in the second log data.
