\title{Disability-adjusted life years (DALYs) accumulator}
\usage{
mb_daly(yld, yll, persons = 1)
}
\arguments{
\item{yld}{Numeric scalar or vector. Years lived with disability
per person.}

\item{yll}{Numeric scalar or vector. Years of life lost per
person (e.g. life expectancy minus age at death).}

\item{persons}{Numeric scalar. Number of persons. Default \code{1}.}
}
\value{
Numeric scalar. Total DALYs (YLD + YLL summed across
persons).
}
\description{
Sums years lived with disability (YLD) and years of life lost
(YLL) across persons. DALY is the global-health analogue of
QALY: lower is better.
}
\details{
\deqn{\text{DALY} = \text{persons} \cdot \sum (YLD + YLL)}

This implementation follows the Global Burden of Disease
definition. Age-weighting and discounting are not applied by
default (the IHME GBD removed both in the 2010 update); add a
discount factor manually if your guidance still requires it.
