Coefficients for Sex Ratio Adjustments in the PMD Method

Description

Data object containing a table of coefficients to be used to adjust the sex ratio in the coherent Pattern Mortality Decline method as implemented in the copmd function. To invoke the adjustment, argument sexratio.adjust should be set to TRUE.

Usage

data(PMDadjcoef)

Format

Data frame containing columns “age”, “intercept”, “lmxf”, “e0f”, “e0f2”, and “gap”. Rows correspond to age groups. The values are estimates of the following regression

\log_{10} mx^M = \beta_0 + \beta_1\log_{10} mx^F + \beta_2 e_0^F + \beta_3 (e_0^F)^2 + \beta_4(e_0^F - e_0^M)

The order of the columns starting with intercept corresponds to the order of the coefficients in the above equation.

Source

The coefficients were estimated and provided by Danan Gu, UN Population Division.
