Synthetic Purposive Sampling Estimator for the Average-Site ATE

Usage

sps_estimator(
  out = NULL,
  estimates_selected = NULL,
  X = NULL,
  selected_sites = NULL
)

Arguments

out

Output from function sps()

estimates_selected

data.frame with two columns: the first column represents estimates of the site-specific ATEs for the selected sites and the second column represents its corresponding standard error. The number of rows is equal to the number of the selected sites and rownames(estimates_selected) should be names of the selected sites.

X

(Optional. Use this only when sites are not selected based on sps(). Default = NULL) Site-level variables for the target population of sites. Row names should be names of sites.

selected_sites

(Optional. Use this only when sites are not selected based on sps(). Default = NULL) Names of sites users selected. This should be a subset of rownames(X).

Value

sps_estimator returns an object of sps_estimator class.

  • average_site_ATE: An estimate of the average-site ATE and its corresponding standard error.

  • site_specific_ATE: Estimates and standard errors for the site-specific ATEs in non-selected sites.

  • bet_se: Estimated between-site standard errors.
