get_one_mannwhitney {drord}  R Documentation 
Compute one estimate of MannWhitney parameter based on a given data set.
Description
Compute one estimate of MannWhitney parameter based on a given data set.
Usage
get_one_mannwhitney(
treat,
covar,
treat_form,
out,
out_levels,
out_form,
out_model
)
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.

treat_form 
The righthand side of a regression formula for the working model of
treatment probability as a function of covariates

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

out_levels 
A numeric vector containing all ordered levels of the
outcome.

out_form 
The righthand 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).

Value
Estimate of MannWhitney parameter for these input data.
