A first set of variables is introduced into a data transaction scoring system. The first set of variables having a maturity level less than a second set of variables previously matured on the data transaction scoring system. The maturity level corresponding to an amount of exposure to the data transaction scoring system. The amount of exposure affecting a degree of precision for the data transaction scoring system. The first set of variables are introduced by expanding a data transaction profile for the data transaction scoring system including second set of variables to further include the first set of variables. Initial values are assigned for the first set of variables based on a statistical model. After such an assignment, scoring of data transactions using the expanded data transaction profile prior to maturing the data transaction system using the first set of variables can be initiated.
