estimate_wmean {drord}

Compute the estimate of the weighted mean parameter based on estimated PMF in each treatment arm.

Description

Compute the estimate of the weighted mean parameter based on estimated PMF in each treatment arm.

Usage

estimate_wmean(
  pmf_est,
  treat,
  out,
  out_levels,
  out_weights,
  treat_prob_est,
  return_cov = TRUE
)

Arguments

pmf_est

List of treatment-specific PMF estimates.

treat

A numeric vector containing treatment status. Missing values are not allowed unless the corresponding entry in out is also missing. Only values of 0 or 1 are treated as actual treatment levels. Any other value is assumed to encode a value for which the outcome is missing and the corresponding outcome value is ignored.

out

A numeric vector containing the outcomes. Missing outcomes are allowed.

out_levels

A numeric vector containing all ordered levels of the outcome.

out_weights

A vector of numeric weights with length equal to the length of out_levels.

treat_prob_est

Estimated probability of treatments, output from call to estimate_treat_prob.

return_cov

If TRUE the estimated covariance matrix is returned.

Value

List with estimates of treatment-specific means and difference in means. If return_cov = TRUE, also includes covariance matrix estimates.
