A method, a system and a computer program product for determining whether a change in value of a data item relating to an entity being tracked within a cohort is statistically and contextually significant. A computer captures a plurality data items relating to the entity being tracked at a time N+1. The value of the data item at time N+1 is compared to a value of a historical data item at time N. If the value of the data item at time N+1 is different from the value of the historical data item at time N, determining that a change has occurred. If a change in a data item has occurred, determining whether the change in the data item is related to the entity being tracked is statistically and contextually significant in n space on multiple dimensions.
