QALY_survival

TODO: use expected QALY over (all-cause) life-table survival probabilities.

QALY_survival(utility = NA, gender = NA, age = NA, start_delay = 0,
  discount_rate = 0.035, utility_method = "add")

Arguments

utility	Vector of values between 0 and 1 (1 - utility loss)
age	Year of age
start_delay	What time delay to origin, to shift discounting
discount_rate	default 3.5%
utility_method	Should the yearly QALYs be summed to a scalar? add or prod
intervals	Time intervals for each utility

Details

Uses the following formula:

$$ QALY = \int_0^\infty S(t) u(t) dt \approx \sum_0^100 S(t) u(t) $$
