  • Publication number: 20220067122
    Abstract: A computer-implemented systems and methods for capping outliers during an experiment test is disclosed. The computer implemented system comprises a memory storing instructions and at least one or more processors. The at least one or more processors may be configured to configured to execute the instructions to determine at least two groups of users comprising a plurality of users; obtain metric data related to each of the plurality of users; calculate a first value and a second value based on the metric data; identify an occurrence of a trigger event, using the metric data, the first value, and the second value; distribute the metric data into capped data and uncapped data and determine a threshold for the capped data; calculate a third value for the capped data and the uncapped data; determine if the capped data threshold has changed based on the third value; and implement at least one capping percentile value upon occurrence of the trigger event.

  • Publication number: 20210350401
    Abstract: A system for experimentation of e-commerce pricing distribution based on time-interleaving includes one or more processors configured to identifying a first set of items from a plurality of items based on one or more item pricing policies. Scheduling the first set of items to be published on a website during a first time slot from a plurality of time slots by applying a scheduling algorithm. Identifying a first subset of substitutable items and a second subset of substitutable items from the first set of items based on one or more item substitution rules. Assigning the first subset of substitutable items with a first pricing policy and the second subset of substitutable items with a second pricing policy. Publishing the first subset of substitutable items and the second subset of substitutable items. Determining pricing distribution data based on monitoring customer interaction.
