Claim 2:
3. The analysis device according to claim 1, wherein
the receiving further receives an input of data, as threshold calculation purpose data, in which requests made to a server by a user are represented in a time series, and
the classifying classifies, for each user who made the requests, the threshold calculation purpose data received by the receiving, and
the analysis device further comprises thirdly extracting, by using each request in the threshold calculation purpose data classified by the classifying as a starting point, for each of the w consecutive requests, the n consecutive requests as the feature values of the threshold calculation purpose data, that calculates scores for each of the w consecutive requests based on the feature values of the threshold calculation purpose data and based on the profiles created by the creating, and calculating the threshold based on an amount of change in the scores in a time series.
