Retrieve Aggregated Stats of Specific Segmentation via REST API

In cases where users might want aggregated stats of a specific segmentation for different reasons, such as checking a hypothesis or collecting data to re-train a model.

For this, users can now leverage Mona's /stats REST API endpoint to retrieve said segmentation stats.

To access Mona's API, first, an accessToken must be generated and added to the request.

Once users have their accessToken they can add it to their authorization and send a POST request with the following mandatory params:

  • "contextClass": the context class of the desired segmentation.
  • "dimension": the segmentation field we are looking for.
  • "targetTimeRange": the time range of the target set. Expected format is an array of timestamps.
  • "comparedTimeRange": the time range of the compared set (benchmark). Expected format is an array of timestamps. If not comparing time periods, set as [null, null].
  • "metric_1_field": the first metric field we wish to get stats of.
  • "metric_2_field": the second metric field we wish to get stats of.
  • "metric_1_type": the type of metric for the corresponding metric field. Possible values are - average, sum, variance, normalized_variance, std, standard_error, interquartile range, and existence ratio.
  • "metric_2_type": the type of metric for the corresponding metric field.
  • "minSegmentSize": the minimum size of segments we want stats for.
  • "sortFunction": the sorting for the segments. Possible values are - SIZE_TOP, SIZE_INC, SIZE_DEC, METRIC_1_TOP, METRIC_1_BOTTOM, METRIC_1_INC, METRIC_1_DEC, METRIC_2_TOP, METRIC_2_BOTTOM, METRIC_2_INC, METRIC_2_DEC

Optional args for segments:

  • "baseline_segment": The baseline of the segments. If not added the baseline is all data. Expecated format is SegmentType.
  • "excluded_segments": Segments to exclude from the data. Expecated format is SegmentListType
  • "target_segments_filter": A filter for the target time period. Expecated format is SegmentType.
  • "compared_segments_filter":A filter for the compared time period. Expecated format is SegmentType.

In the following example, we are looking for the stats of different segments in the "purpose" segmentation, in a 7 days time range, compared to 2 weeks prior to that, with the average of "credit_score" and "loan_taken".
The segments filters will allow us to look only at the "city": "Arkansas_Fort Smith", "offered_amount": 140 ≤ X ≥ 2100, while excluding "occupation": "no category", and in the target set looking at "stage": "inference" and in the benchmark set at "stage": "train".
