\title{Incremental net benefit}
\usage{
mb_inb(delta_cost, delta_effect, wtp)
}
\arguments{
\item{delta_cost}{Numeric scalar. Incremental cost of B over A.}

\item{delta_effect}{Numeric scalar. Incremental effect of B
over A.}

\item{wtp}{Numeric scalar. Willingness-to-pay per unit of effect
(e.g. the NICE QALY threshold in a health context).}
}
\value{
Numeric scalar. INB in the units of \code{delta_cost}. INB > 0
means B is cost-effective at the supplied WTP.
}
\description{
Computes the incremental net benefit (INB) of B over A at a
single willingness-to-pay threshold. Equivalent to the ICER
framing on a monetary scale.
}
\details{
\deqn{\text{INB} = \lambda \cdot \Delta E - \Delta C}
Equivalent to ICER comparison: INB > 0 iff ICER < WTP (when
effect change is positive).
}
\examples{
mb_inb(delta_cost = 50000, delta_effect = 2, wtp = 30000)
