pt_designer: Declare a process tracing design from a causal model

In macartan/biqq: Package for BIQQ analysis as described in Jacobs, Humphreys (2016)

Description

Warning – do not use redesign with design produced from this designer

Usage

pt_designer(true_model, estimation_model = true_model, ops, query,
  strategy = TRUE, N = 1, sims = 2000)

Arguments

true_model	A model: not available to applied researcher
estimation_model	A model: as supposed by applied researcher
ops	Operations that form part of the query
query	The query
strategy	Data gathering strateg – a vector of TRUES or FALSES indicating which nodes are observed
N	Population for which inferences might be made. Estimand averages over these.
sims	Precision for posterior calculation

Examples

model <- pt_model()
ops = list(c(0, NA, NA, NA, NA), c(1, NA, NA, NA, NA))
query = function(x) (x[[1]][5] ==1) & (x[[2]][5] == 0)
design <- pt_designer(model, ops = ops, query = query, sims = 500)
draw_estimates(design)
