Convert per-person expected value of information to the population expected value of information, given a discount rate over some time horizon.
pop_voi(voi, pop, time, dis = 0.035)A vector of population VoI estimates.
Vector of estimates of any per-person value of information
measure, e.g. the evsi column of the data frame returned by
evsi or the correspondingly-named columns of the
data frames returned by evppi or evpi.
Size of the population who would be affected by the decision.
Time horizon over which discounting will be applied.
Discount rate used when converting per-person to population EVSI.
Calculated as voi*pop/dis*(1 - exp(-dis*time)), or voi*pop
if the discount rate is zero. This is a continuous-time variant
of the typical discrete-time discounting formula.
Any arguments may be supplied as vectors, in which case, all arguments are replicated to the length of the longest argument.
