Example of irregularity detection. Note: The figure displays the time series of cashless payments at PoS in the canton of Fribourg (between 09-08-2021 and 07-11-2021). The gray border indicates the confidence limits, while the dots represent observations of a single day. Red dots indicate irregularities: the one on 01-11-2021 is an economic irregularity due to a local holiday; the one on the far right is due to the late processing of transactions occurring on the last day of the sample (a Sunday), which was corrected in a subsequent data update.
