Get estimate of the area between two Qini curves with paired standard errors.

Given two Qini curves, \(Q_a\) and \(Q_b\), and a maximum spend \(\bar B\), get an estimate of the integrated difference \(\int_{0}^{\bar B} (Q_a(B) - Q_b(B))dB\).

integrated_difference(object.lhs, object.rhs, spend)

Arguments

object.lhs	A maq object \(Q_a\) to subtract from.
object.rhs	A maq object \(Q_b\) to subtract with.
spend	The spend level \(\bar B\).

Value

An estimate of the area between the two curves along with standard errors.
