c-WeightedStudySpecification-method: Concatenate weights

In propertee: Standardization-Based Effect Estimation with Optional Prior Covariance Adjustment

Concatenate weights

Description

Given several variations of weights generated from a single StudySpecification, combine into a single weight.

Usage

## S4 method for signature 'WeightedStudySpecification'
c(x, ..., warn_dichotomy_not_equal = FALSE)

Arguments

x	.. a WeightedStudySpecification object, typically created from ate() or ett()
...	any number of additional WeightedStudySpecification objects with equivalent StudySpecification to x and eachother
warn_dichotomy_not_equal	if FALSE (default), WeightedStudySpecifications are considered equivalent even if their dichotomy differs. If TRUE, a warning is produced.

Details

Concatenating WeightedStudySpecification objects with c() requires both individual WeightedStudySpecification objects to come from the same StudySpecification and have the same target (e.g all created with ate() or all created with ett(), no mixing-and-matching). All arguments to c() must be WeightedStudySpecification.

WeightedStudySpecification objects may be concatenated together even without having the same @dichotomy slot. This procedure only prompts a warning for differing dichotomies if the argument warn_dichotomy_not_equal is set to TRUE.

Value

A numeric vector with the weights concatenated in the input order.

Examples

data(simdata)
spec <- rct_spec(z ~ unit_of_assignment(uoa1, uoa2), data = simdata)
w1 <- ate(spec, data = simdata[1:30,])
w2 <- ate(spec, data = simdata[31:40,])
w3 <- ate(spec, data = simdata[41:50,])
c_w <- c(w1, w2, w3)
c(length(w1), length(w2), length(w3), length(c_w))

spec <- rct_spec(dose ~ unit_of_assignment(uoa1, uoa2), data = simdata)
w1 <- ate(spec, data = simdata[1:10, ], dichotomy = dose >= 300 ~ .)
w2 <- ate(spec, data = simdata[11:30, ], dichotomy = dose >= 200 ~ .)
w3 <- ate(spec, data = simdata[31:50, ], dichotomy = dose >= 100 ~ .)
c_w <- c(w1, w2, w3)
