#' Default daily hazard of spontaneous live birth
#'
#' Approximate daily hazard rates of spontaneous live birth by gestational
#' day, from day 1 through day 301 of gestation. Hazard rates are set to 0 for
#' gestational days 1 through 153, reflecting that 22 weeks of gestation is
#' approximately the lower gestational-age limit at which active neonatal
#' care is considered in Norwegian clinical practice. Positive hazard rates
#' begin at gestational day 154.
#'
#' @format A numeric vector of length 301. Element `i` corresponds to
#' gestational day `i`.

#' Default daily hazard of non-spontaneous live birth
#'
#' Approximate daily hazard rates of non-spontaneous live birth by gestational
#' day, from day 1 through day 301 of gestation. Hazard rates are set to 0 for
#' gestational days 1 through 153, reflecting that 22 weeks of gestation is
#' approximately the lower gestational-age limit at which active neonatal
#' care is considered in Norwegian clinical practice. Positive hazard rates

#' Default daily hazard of late miscarriage/stillbirth
#'
#' Approximate daily hazard rates of late miscarriage/stillbirth by gestational
#' day, from day 1 through day 301 of gestation. Hazard rates are set to 0 for
#' gestational days 1 through 83 because the data used to specify the default
#' hazard do not include early miscarriage. Positive hazard rates begin at
#' gestational day 84.

#' Approximate daily hazard rates of exposure by gestational day, from day 1
#' through day 301 of gestation.
