Arguments

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.
covar	A `data.frame` containing the covariates to include in the working proportional odds model.
out	A `numeric` vector containing the outcomes. Missing outcomes are allowed.
treat_form	The right-hand side of a regression formula for the working model of treatment probability as a function of covariates
out_levels	A `numeric` vector containing all ordered levels of the outcome.
out_form	The right-hand side of a regression formula for the working proportional odds model. NOTE: THIS FORMULA MUST NOT SUPPRESS THE INTERCEPT.
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).

Estimates of Mann-Whitney parameter for a particular bootstrap sample.
