S4BuyseTestcoef {BuyseTest}  R Documentation 
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 
endpoint 
[character] for which endpoint(s) the summary statistic should be output?
If 
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 
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 MannWhitney 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).
