kin_time_variant_2sex {DemoKin}

Estimate kin counts in a time variant framework (dynamic rates) in a two-sex framework (Caswell, 2022)

Description

Two-sex matrix framework for kin count estimates with varying rates. This produces kin counts grouped by kin, age and sex of each relatives at each Focal´s age. For example, male cousins from aunts and uncles from different sibling's parents are grouped in one male count of cousins.

Usage

kin_time_variant_2sex(
  pf = NULL,
  pm = NULL,
  ff = NULL,
  fm = NULL,
  sex_focal = "f",
  birth_female = 1/2.04,
  pif = NULL,
  pim = NULL,
  nf = NULL,
  nm = NULL,
  output_cohort = NULL,
  output_period = NULL,
  output_kin = NULL,
  list_output = FALSE
)

Arguments

pf

numeric. A vector (atomic) or matrix with probabilities (or survival ratios, or transition between age class in a more general perspective) with rows as ages (and columns as years in case of matrix, being the name of each col the year).

pm

numeric. A vector (atomic) or matrix with probabilities (or survival ratios, or transition between age class in a more general perspective) with rows as ages (and columns as years in case of matrix, being the name of each col the year).

ff

numeric. Same as pf but for fertility rates.

fm

numeric. Same as pm but for fertility rates.

sex_focal

character. "f" for female or "m" for male.

birth_female

numeric. Female portion at birth. This multiplies f argument. If f is already for female offspring, this needs to be set as 1.

pif

numeric. For using some specific age distribution of childbearing for mothers (same length as ages). Default NULL.

pim

numeric. For using some specific age distribution of childbearing for fathers (same length as ages). Default NULL.

nf

numeric. Same as pf but for population distribution (counts or ⁠%⁠). Optional.

nm

numeric. Same as pm but for population distribution (counts or ⁠%⁠). Optional.

output_cohort

integer. Vector of year cohorts for returning results. Should be within input data years range.

output_period

integer. Vector of period years for returning results. Should be within input data years range.

output_kin

character. kin types to return: "m" for mother, "d" for daughter,...

list_output

logical. Results as a list with years elements (as a result of output_cohort and output_period combination), with a second list of output_kin elements, with focal´s age in columns and kin ages in rows (2 * ages, last chunk of ages for death experience). Default FALSE

Details

See Caswell (2022) for details on formulas.

Value

A data.frame with year, cohort, Focal´s age, related ages, sex and type of kin (for example d is daughter, oa is older aunts, etc.), including living and dead kin at that age and sex.
