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: [character] label modality A

  • modalityID.B: [character] label modality B

  • nR: [numeric] number of readers

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

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

• There are six fixed effects:

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

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

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

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

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

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

• There are six random effects that are independent of modality

  • var_r.neg: [numeric] variance of random reader effect

  • var_c.neg: [numeric] variance of random case effect

  • var_rc.neg: [numeric] variance of random reader by case effect

  • var_r.pos: [numeric] variance of random reader effect

  • var_c.pos: [numeric] variance of random case effect

  • var_rc.pos: [numeric] variance of random reader by case effect

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

  • var_r.Aneg: [numeric] variance of random reader effect

  • var_c.Aneg: [numeric] variance of random case effect

  • var_rc.Aneg: [numeric] variance of random reader by case effect

  • var_r.Apos: [numeric] variance of random reader effect

  • var_c.Apos: [numeric] variance of random case effect

  • var_rc.Apos: [numeric] variance of randome reader by case effect

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

  • var_r.Bneg: [numeric] variance of random reader effect

  • var_c.Bneg: [numeric] variance of random case effect

  • var_rc.Bneg: [numeric] variance of random reader by case effect

  • var_r.Bpos: [numeric] variance of random reader effect

  • var_c.Bpos: [numeric] variance of random case effect

  • var_rc.Bpos: [numeric] variance of randome reader by case effect
