In timriffe/DemoTools: Standardize, Evaluate, and Adjust Demographic Data

calculate a single age lifetable

Description

Fuller description forthcoming

Usage

lt_single_mx(
  nMx,
  Age = 1:length(nMx) - 1,
  radix = 1e+05,
  a0rule = "ak",
  Sex = "m",
  region = "w",
  IMR = NA,
  mod = TRUE,
  SRB = 1.05,
  OAG = TRUE,
  OAnew = max(Age),
  extrapLaw = NULL,
  extrapFrom = max(Age),
  extrapFit = NULL,
  ...
)

Arguments

nMx	numeric. Vector of mortality rates in abridged age classes.
Age	integer. A vector of ages of the lower integer bound of the age classes.
radix	numeric. Lifetable radix, l0. Default 100000.
a0rule	character. Either "ak" (default) or "cd".
Sex	character. Either male "m", female "f", or both "b".
region	character. North, East, South, or West: "n", "e", "s", "w". Default "w".
IMR	numeric. Infant mortality rate q0, in case available and nqx is not specified. Default NA.
mod	logical. If "un" specified for axmethod, whether or not to use Nan Li's modification for ages 5-14. Default TRUE.
SRB	the sex ratio at birth (boys / girls), default 1.05
OAG	logical. Whether or not the last element of nMx (or nqx or lx) is an open age group. Default TRUE.
OAnew	integer. Desired open age group (5-year ages only). Default max(Age). If higher then rates are extrapolated.
extrapLaw	character. If extrapolating, which parametric mortality law should be invoked? Options include "Kannisto", "Kannisto_Makeham", "Makeham", "Gompertz", "GGompertz", "Beard", "Beard_Makeham", "Quadratic". Default "Kannisto" if the highest age is at least 90, otherwise "makeham". See details.
extrapFrom	integer. Age from which to impute extrapolated mortality.
extrapFit	integer vector. Ages to include in model fitting. Defaults to all ages > =60.
...	Other arguments to be passed on to the MortalityLaw function.

• nqx numeric. Age-specific conditional death probabilities.

• lx numeric. Lifetable survivorship

• ndx numeric. Lifetable deaths distribution.

• nLx numeric. Lifetable exposure.

• Sx numeric. Survivor ratios in uniform 5-year age groups.

• Tx numeric. Lifetable total years left to live above age x.
