Abstract
A facility for estimating a value relating to an occurrence is described. The facility receives a first occurrence specifying a first value for each of a plurality of independent variables that include a distinguished independent variable designated to be monotonically linked to a dependent variable. The facility subjects the first independent variable values specified by the received occurrence to a statistical model to obtain a first value of the dependent variable. The facility receives a second occurrence specifying a second value for each of the plurality of independent variables (the second values varying from the first values in a first direction). The facility subjects the second independent variable values to the statistical model to obtain a second value of the dependent variable, the second value of the dependent variable being guaranteed not to vary from the first value of the dependent variable in a second direction opposite the first direction.
