take a prepared DHS sibling dataset and add maternal death info

Usage

add_maternal_deaths(sib_df, keep_missing = FALSE, verbose = TRUE)

Arguments

sib_df: the prepped DHS dataset (probably from prep_dhs_sib_histories)
keep_missing: should we keep reported sibs that are missing sex or survival status?
verbose: report detailed summaries?

Value

a dataframe with columns sib.preg_related.death.date and sib.maternal.death.date added

Details

This function checks to see if there is a column called sib.died.accident. If so, then it is possible to estimate whether or not each death is maternal; the resulting death dates are in the column sib.maternal.death.date.

For siblings, you should be sure to include

sib.death.date (the date of the sibling's death)
sib.alive (whether or not the sib is alive)
sib.sex (the sex of the sibling).
