Estimating Public and Private Sector Contraceptive Market Supply Shares

Description

Family Planning programs and initiatives typically use nationally representative surveys to estimate key indicators of a country’s family planning progress. However, in recent years, routinely collected family planning services data (Service Statistics) have been used as a supplementary data source to bridge gaps in the surveys. The use of service statistics comes with the caveat that adjustments need to be made for missing private sector contributions to the contraceptive method supply chain. Evaluating the supply source of modern contraceptives often relies on Demographic Health Surveys (DHS), where many countries do not have recent data beyond 2015/16. Fortunately, in the absence of recent surveys we can rely on statistical model-based estimates and projections to fill the knowledge gap. We present a Bayesian, hierarchical, penalized-spline model with multivariate-normal spline coefficients, to account for across method correlations, to produce country-specific,annual estimates for the proportion of modern contraceptive methods coming from the public and private sectors. This package provides a quick and convenient way for users to access the DHS modern contraceptive supply share data at national and subnational administration levels, estimate, evaluate and plot annual estimates with uncertainty for a sample of low- and middle-income countries. Methods for the estimation of method supply shares at the national level are described in Comiskey, Alkema, Cahill (2022) .

Functions in mcmsupply (1.1.1)

national_FPsource_format

A checklist for ensuring national-level custom data is appropriate to be used for estimation
plot_estimates

Wrapper function to plot the JAGS estimates
pull_estimates

Function to pull method-supply share median estimates and credible intervals for a given year and country.
run_jags_model

Wrapper function to run the jags model for estimating the proportion of modern contraceptive methods supplied by the public & private Sectors using a Bayesian hierarchical penalized spline model for the national and subnational administration levels
national_tau_alpha_cms_hat_bivarlogitnorm

The median estimates of the precision for the national-level country, sector-, method-specific intercepts in the multi-country national model. This vector is used to inform the precision in the Normal prior of the national-level intercept in single-country national models.
subnat_FPsource_format

A checklist for ensuring subnational-level custom data is appropriate to be used for estimation
national_varcov_order_bivarlogitnormal

The order of observations to join the variance-covariance array data and the DHS survey observations for the proportion of modern contraceptives supplied by the public and private sectors at the national level
subnational_inv.sigma_delta_hat

The median estimate for the subnational-level precision matrix of the delta.k terms in the multi-country subnational model. This array is used to inform the multi-variate normal prior in the single-country subnational model.
national_estimated_correlations_bivarlogitnormal

The estimated national-level correlations between the rates of change in methods
national_theta_rms_hat_bivarlogitnorm

The median estimates of the national-level sub-continental, sector-, method-specific intercepts in the multi-country national model. This array is used to inform the Normal prior of the country-level intercept in the single-country national model.
subnat_FPsource_data

DHS survey observations for the proportion of modern contraceptives supplied by the public and private sectors at the subnational administration level.
subnational_estimated_correlations

The estimated subnational-level correlations between the rates of change in methods
subnational_tau_alpha_pms_hat

subnational_tau_alpha_pms_hat The median estimates of the precision for the subnational-level country, sector-, method-specific intercepts in the multi-country subnational model. This vector is used to inform the precision in the Normal prior of the subnational-level intercept in single-country subnational models.
subnational_alpha_cms_hat

The median estimates of the subnational-level country, sector-, method-specific intercepts in the multi-country subnational model. This array is used to inform the Normal prior of the subnational-level intercept in the single-country subnational model.
national_inv_sigma_delta_hat_bivarlogitnorm

The median estimate for the national-level variance-covariance matrix of the delta.k terms in the multi-country national model.
Country_and_area_classification

The Country and area classification according to the United Nations Standaistical Division, Standard country or area codes for statistical use (M49). Adapted for use in FP2030 by the Track20 project. A subset of data from the United Nations country classifications
get_data

Wrapper function that retrieves the DHS data used for modelling the proportion of modern contraceptives supplied by the public and private sectors at the national and subnational administration levels.
get_subnational_modelinputs

Get JAGS model inputs
get_posterior_P_samps

Function to pull the complete posterior sample for the national method-supply share estimates. Functionality for the subnational models is still under development.
country_names

The names of the countries with national and subnational administration level data stored
national_FPsource_VARCOV_bivarlogitnormal

An array of variance-covariance matrices corresponding to the DHS survey observations for the proportion of modern contraceptives supplied by the public and private sectors at the national level
mcmsupply-package

mcmsupply: Estimating Public and Private Sector Contraceptive Market Supply Shares
DEFT_DHS_database

DEFT_DHS_database A database of the design effects for some of the DHS surveys in the national and subnational datasets. Due to due to multistage and clustering of the DHS sample, the average standard error is increased by a design effect (DEFT) factor over that in an equivalent simple random sample.
national_FPsource_data

DHS survey observations for the proportion of modern contraceptives supplied by the public and private sectors at the national level
