An array of variance-covariance matrices transformed onto the logit-scale via the delta method. Each matrix corresponds to the DHS survey logit-transformed observations for the proportion of modern contraceptives supplied by the public and private sectors at the national level

Usage

national_FPsource_VARCOV_bivarlogitnormal

Format

national_FPsource_VARCOV_bivarlogitnormal

An array of 2x2 matrices for each of the 608 observations in the national_FPsource_data. Each 2x2 array corresponds to the variance of the public and private sectors on the diagonal and their corresponding covariances on the off-diagonal.

Source

The variance-covariance matrices are calculated using the survey R package: prop_mat <- svyby(~I(sector_categories), ~I(modern_method_source), design=d.s, svymean, covmat=TRUE) vcov_matrix <- vcov(prop_mat) function.
