Arguments

mannwhitney_est	The point estimates for log-odds.
cdf_est	The estimated conditional CDF.
pmf_est	The estimated conditional PMF.
treat_prob_est	Estimated probability of treatments, output from call to estimate_treat_prob.
treat_form	The right-hand side of a regression formula for the working model of treatment probability as a function of covariates
out_form	The right-hand side of a regression formula for the working proportional odds model. NOTE: THIS FORMULA MUST NOT SUPPRESS THE INTERCEPT.
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.
ci	A vector of characters indicating which confidence intervals should be computed ("bca" and/or "wald")
out	A numeric vector containing the outcomes. Missing outcomes are allowed.
alpha	Confidence intervals have nominal level 1-alpha.
nboot	Number of bootstrap replicates used to compute bootstrap confidence intervals.
out_levels	A numeric vector containing all ordered levels of the outcome.
covar	A data.frame containing the covariates to include in the working proportional odds model.
out_model	Which R function should be used to fit the proportional odds model. Options are "polr" (from the MASS package), "vglm" (from the VGAM package), or "clm" (from the ordinal package).
