da_compare: compare diagnostic accuracy measures for 2 binary tests...

In lbraglia/lbdiag: Diagnostic Accuracy Miscellaneous Utilities

compare diagnostic accuracy measures for 2 binary tests evaluated in a paired setting (each test evaluated each patients) having a reference tandard

Description

compare diagnostic accuracy measures for 2 binary tests evaluated in a paired setting (each test evaluated each patients) having a reference tandard

Usage

da_compare(
  test1 = NULL,
  test2 = NULL,
  refstd = NULL,
  test1_lab = "test1",
  test2_lab = "test2",
  alpha = 0.05,
  boot_R = 10000,
  da_params = list(),
  boot_parallel = "multicore",
  boot_ncpus = 8L
)

Arguments

test1	oldest test available, logical value with FALSE = non diseased and TRUE diseased or factor with two levels
test2	new test, same coding as test1
refstd	reference standard diagnosis same coding as test1
test1_lab	test 1 label/name
test2_lab	test 2 label/name
alpha	Type I error
boot_R	bootstrap repetition
boot_parallel	use parallel
boot_ncpus	number of cpus dedicated to bootstrapping

Examples

db  <- dadb(tp = 70, fp = 20, fn = 30, tn = 80)
db2 <- dadb(tp = 50, fp = 45, fn = 50, tn = 55)
db$test2 <- db2$test
## test2 is worst than test
acc <- da_compare(test1 = db$test, test2 = db$test2, refstd = db$refstd)
