Examples
## Load example data
data(VanDyke)
## Return the first parts of an object
head(VanDyke)
## Extract unique modalities
unique(VanDyke$treatment)
## Extract Unique readers
unique(VanDyke$reader)
## Create binary test results (Y_ijk)
VanDyke$Y <- as.numeric(VanDyke$rating >= 3)
## Example usage of MRMCbinary function:
# When comparing the sensitivities and specificities between modalities
modality_result <- MRMCbinary(data = VanDyke, Modality = treatment, Reader = reader,
Case = case, D = truth, Y = Y, measure = "All",
effect = "Modality", interaction = NULL,
reference.Modality = "1", reference.Reader = NULL)
summary(modality_result, digits = 3)
# When comparing the sensitivities and specificities between readers
reader_result <- MRMCbinary(data = VanDyke, Modality = treatment, Reader = reader,
Case = case, D = truth, Y = Y, measure = "All",
effect = "Reader", interaction = NULL,
reference.Modality = NULL, reference.Reader = "1")
summary(reader_result, digits = 3)
# When comparing the sensitivities and specificities
# between modalities and between readers together
# not considering interaction between modalities and readers
both_result_wo_int <- MRMCbinary(data = VanDyke, Modality = treatment, Reader = reader,
Case = case, D = truth, Y = Y, measure = "All",
effect = "Both", interaction = FALSE,
reference.Modality = "1", reference.Reader = "1")
summary(both_result_wo_int, digits = 3)
# When comparing the sensitivities and specificities
# between modalities and between readers together
# considering interaction between modalities and readers
both_result_with_int <- MRMCbinary(data = VanDyke, Modality = treatment, Reader = reader,
Case = case, D = truth, Y = Y, measure = "All",
effect = "Both", interaction = TRUE,
reference.Modality = "1", reference.Reader = "1")
summary(both_result_with_int, digits = 3)
