S4BuyseTest-coef {BuyseTest}

Extract Summary Statistics from GPC

Description

Extract summary statistics (net benefit, win ratio, ...) from GPC.

Usage

## S4 method for signature 'S4BuyseTest'
coef(
  object,
  endpoint = NULL,
  statistic = NULL,
  strata = FALSE,
  cumulative = NULL,
  resampling = FALSE,
  simplify = TRUE,
  ...
)

Arguments

object

a S4BuyseTest object, output of BuyseTest.

endpoint

[character] for which endpoint(s) the summary statistic should be output? If NULL returns the summary statistic for all endpoints.

statistic

[character] the type of summary statistic. See the detail section.

strata

[character vector] the strata relative to which the statistic should be output. Can also be "global" or FALSE to output the statistic pooled over all strata, or TRUE to output each strata-specific statistic.

cumulative

[logical] should the summary statistic be cumulated over endpoints? Otherwise display the contribution of each endpoint.

resampling

[logical] should the summary statistic obtained by resampling be output?

simplify

[logical] should the result be coerced to the lowest possible dimension?

...

ignored.

Details

One of the following statistic can be specified:

• "netBenefit": returns the net benefit.

• "winRatio": returns the win ratio.

• "favorable": returns the proportion in favor of the treatment (also called Mann-Whitney parameter).

• "unfavorable": returns the proportion in favor of the control.

• "unfavorable": returns the proportion of neutral pairs.

• "unfavorable": returns the proportion of uninformative pairs.

• "count.favorable": returns the number of pairs in favor of the treatment.

• "count.unfavorable": returns the number of pairs in favor of the control.

• "count.neutral": returns the number of neutral pairs.

• "count.uninf": returns the number of uninformative pairs.

Value

When resampling=FALSE and simplify=FALSE, a matrix (strata, endpoint). When resampling=FALSE and simplify=FALSE, an array (sample, strata, endpoint).
