ineq_rel_eta_dag: ineq_rel_edag

In alysonvanraalte/LifeIneq: Calculate indices of lifespan variation

ineq_rel_edag

Description

Calculate a lifetable column for the elasticity of age at death, which is analogous to the Keyfitz-Leser H measure.

Usage

ineq_rel_eta_dag(age, dx, lx, ex, ax, check = TRUE, distribution_type = "aad")

Arguments

age	numeric. vector of lower age bounds.
dx	numeric. vector of the lifetable death distribution.
lx	numeric. vector of the lifetable survivorship.
ex	numeric. vector of remaining life expectancy.
ax	numeric. vector of the average time spent in the age interval of those dying within the interval.
check	logical. Shall we perform basic checks on input vectors? Default TRUE

Details

This method is implemented for the sake of completeness, since e^\dagger and H give the absolute and relative shortfall metrics, we've included eta_dag and rel_eta_dag to give age-at-death versions of these. We're not aware of anyone having used this formulation, and we do not offer a demographic interpretation of the scale of this metric, but we do point out that the conditional shape over age is qualitatively similar to other conditional relative measures from attainment (achieved age) distributions.

Examples

data(LT)
# A vector containing the conditional rel_eta_dag values
H = ineq_rel_edag(age=LT$Age,dx=LT$dx,lx=LT$lx,ex=LT$ex,ax=LT$ax)
# The H from birth
H[1]
# The H conditional upon survival to age 10
