A Reference Class to deal with RCT dataset
Currently working with binary response only. Continous will come, one day. Two-levels treatment only as well.
data
field should be as described, however if virtual twins won't used
interactions, there is no need to transform factors. See
formatRCTDataset for more details.
data
Data.frame with format: Y,T,X_{1}, …, X_{p}. Y must be two levels factor if type is binary. T must be numeric or integer.
screening
Logical, set to FALSE
Set to TRUE
to use
varimp
in trees computation.
varimp
Character vector of important variables to use in trees computation.
delta
Numeric representing the difference of incidence between treatments.
type
Character : binary or continous. Only binary is currently available.
computeDelta()
Compute delta value.
getData(interactions = F)
Return dataset. If interactions is set to T, return data with treatement interactions
getFormula()
Return formula : Y~T+X1+...+Xp. Usefull for cforest function.
getIncidences(rule = NULL)
Return incidence table of data if rule set to NULL. Otherwise return incidence for the rule.
getX(interactions = T, trt = NULL)
Return predictors (T,X,X*T,X*(1-T)). Or (T,X) if interactions is FALSE. If trt is not NULL, return predictors for T = trt
getXwithInt()
Return predictors with interactions. Use VT.object::getX(interactions = T) instead.
getY(trt = NULL)
Return outcome. If trt is not NULL, return outcome for T = trt.
switchTreatment()
Switch treatment value.
