#### Documented in summary.CIMTx_ATE_posterior

#' Summarize a CIMTx_ATE_posterior object
#'
#' @param object a \code{CIMTx_ATE_posterior} object
#' obtained with \code{\link{ce_estimate}} function.
#' @param ... further arguments passed to or from other methods.
#'
#' @return a list with w*(w-1)/2 elements for ATE effect.
#' Each element of the list contains the estimation,
#' standard error, lower and upper 95\% CI for RD/RR/OR.
