The package is developed according to the DHS methodology of calculating the fertility indicators  outlined in the "DHS Guide to Statistics" (Rutstein and Rojas 2006,

Description: Calculates key indicators such as fertility rates (Total Fertility Rate (TFR), General Fertility Rate (GFR),
and Age Specific Fertility Rate (ASFR)) using Demographic and Health Survey (DHS) women/individual data,
and childhood mortality rates such as Neonatal Mortality Rate (NNMR), Post-neonatal Mortality Rate (PNNMR),
Infant Mortality Rate (IMR), Child Mortality Rate (CMR), and Under-5 Mortality Rate (U5MR).
In addition to the indicators, the 'DHS.rates' package estimates precision indicators such as Standard Error (SE),
Design Effect (DEFT), Relative Standard Error (RSE) and Confidence Interval (CI).
The package is developed according to the DHS methodology of calculating the fertility indicators and
the childhood mortality rates  outlined in the
