dot-make_uoa_ids: Make ID's to pass to the 'cluster' argument of 'vcov_tee()'

In propertee: Standardization-Based Effect Estimation with Optional Prior Covariance Adjustment

Make ID's to pass to the cluster argument of vcov_tee()

Description

.make_uoa_ids() returns a factor vector of cluster ID's that align with the order of the units of observations' contributions in estfun.teeMod(). This is to ensure that when vcov_tee() calls sandwich::meatCL(), the cluster argument aggregates the correct contributions to estimating equations within clusters.

Usage

.make_uoa_ids(x, vcov_type, cluster = NULL, ...)

Arguments

x	a fitted teeMod object
vcov_type	a string indicating model-based or design-based covariance estimation. Currently, "MB", "CR", and "HC" are the only strings registered as indicating model-based estimation.
cluster	character vector or list; optional. Specifies column names that appear in both the covariance adjustment and direct adjustment model dataframes. Defaults to NULL, in which case unit of assignment columns indicated in the StudySpecification will be used for clustering. If there are multiple clustering columns, they are concatenated together for each row and separated by "_".
...	arguments passed to methods

Value

A vector with length equal to the number of unique units of observation used to fit the two models. See Details of estfun.teeMod() for the method for determining uniqueness.
