fit_GUI_Shiny_MRMC: Fit with GUI via Shiny (in case of MRMC)

Description

Fit a Bayesian model with GUI.

Revised 2019 Nov.

Usage

fit_GUI_Shiny_MRMC(
  DF = data.frame(m = as.integer(BayesianFROC::dd$m), q =
    as.integer(BayesianFROC::dd$q), c = as.integer(BayesianFROC::dd$c), h =
    as.integer(BayesianFROC::dd$h), f = as.integer(BayesianFROC::dd$f)),
  DF_MQC = data.frame(M = max(DF$m), Q = max(DF$q), C = max(DF$c)),
  NL.max = 1111,
  NI.max = 1111,
  NL.initial = 142,
  NI.initial = 199,
  seed.initial.of.MCMC = 237410,
  MCMC.chains.max = 4
)

Arguments

DF

A dataframe, cosisting of five vectors: reader ID, modality ID, confidence levels, hits, false alarms.

initial data to be fited

DF_MQC

A data frame, consisting of three numbers, i.e., the number of modalities, readers, confidence levels. Of course, these numbers should be compatible with the variable DF.

NL.max

max number of bins indicating the maximal number in which the number of lesions can move

NI.max

max number of bins indicating the maximal number in which the number of imagegs can move

NL.initial

Natural number indicating the initial number of lesions, Default value =142.

NI.initial

Natural number indicating the initial number of images, Default value =199.

seed.initial.of.MCMC

positive integers indicating the initial seed of MCMC sampling. Default is 1234.

MCMC.chains.max

max number of bins indicating number of MCMC chains

Value

None

Details

In what follows, we assume that our dataset has more than two readers or modalities, namely, our dataset is MRMC case. The term imaging modality, we mean a set of imaging methods such as MRI, CT, PET, etc.
