## roeMetzConfigs

### Description

This is a data frame containing the configuration parameters used in Roe1997_Acad-Radiol_v4p298. Each row corresponds to one of the twelve configurations appearing in Table 1 of that paper in a format that can be the input to `sim.gRoeMetz`.

### Details

The columns of this data frame are as follows

- Experiment labels and size

  - modalityID.A: [chr] label modality A

  - modalityID.B: [chr] label modality B

  - nR: [num] number of readers

  - nC.neg: [num] number of signal-absent cases

  - nC.pos: [num] number of signal-present cases

- There are six fixed effects:

  - mu.neg: [num] signal-absent (neg, global mean)

  - mu.pos: [num] signal-present (pos, global mean)

  - mu.Aneg: [num] modality A signal-absent (Aneg, modality effect)

  - mu.Bneg: [num] modality B signal-absent (Bneg, modality effect)

  - mu.Apos: [num] modality A signal-present (Apos, modality effect)

  - mu.Bpos: [num] modality B signal-present (Bpos, modality effect)

- There are six random effects that are independent of modality

  - var_r.neg: [num] variance of random reader effect

  - var_c.neg: [num] variance of random case effect

  - var_rc.neg: [num] variance of random reader by case effect

  - var_r.pos: [num] variance of random reader effect

  - var_c.pos: [num] variance of random case effect

  - var_rc.pos: [num] variance of random reader by case effect

- There are six random effects that are specific to modality A

  - var_r.Aneg: [num] variance of random reader effect

  - var_c.Aneg: [num] variance of random case effect

  - var_rc.Aneg: [num] variance of random reader by case effect

  - var_r.Apos: [num] variance of random reader effect

  - var_c.Apos: [num] variance of random case effect

  - var_rc.Apos: [num] variance of randome reader by case effect

- There are six random effects that are specific to modality B

  - var_r.Bneg: [num] variance of random reader effect

  - var_c.Bneg: [num] variance of random case effect

  - var_rc.Bneg: [num] variance of random reader by case effect

  - var_r.Bpos: [num] variance of random reader effect

  - var_c.Bpos: [num] variance of random case effect

  - var_rc.Bpos: [num] variance of randome reader by case effect
