This function contained an error, and is deprecated. Please use function e0_to_lifetab_logit() instead.

Usage

ex_to_lifetab_brass(
  target,
  standard,
  infant = c("constant", "linear", "CD", "AK"),
  child = c("constant", "linear", "CD"),
  closed = c("constant", "linear"),
  open = "constant",
  radix = 1e+05,
  suffix = NULL
)

Arguments

target

A data frame containing a variable called "ex", and possibly other varibles. See Details.

standard

A data frame containing variables called age and lx, and possibly others. See Details.

infant, child, closed, open

Methods used to calculate life expectancy. See lifetab() for details.

radix

Initial population for the lx column in the derived life table(s). Default is 100000.

suffix

Optional suffix added to life table columns.

Value

A tibble.

Details

Function ex_to_lifetab_brass() used formula

$$\text{logit}(l_x^{\text{B}}) \approx \alpha + \beta \text{logit}(l_x^{\text{A}})$$,

instead of the conventional

$$\text{logit}(1-l_x^{\text{B}}) \approx \alpha + \beta \text{logit}(1-l_x^{\text{A}})$$.
