Abstract: System and methods are provided estimating long-term effects of system changes associated with a user interface without conducting long-term testing. In a first deployment region, a system change is released during a time period. A second deployment region does not have the system change released in the same time period. Historical data is received from both deployment regions associated with the time period. The user interface analysis system determines features from the historical data and determines a synthetic control sub-group from those features that correspond to features for a sub-group in the first deployment region. The user interface analysis system calculates a control outcome metric for the control sub-group and calculates an effect metric as a difference between a first outcome metric for the sub-group from the first deployment region and the control outcome metric.
