Structure and module numbering

There are 6 modules (each with 6 items) numbered as follows

stage1 stage2 stage3
M6
M3
M1 M5
M2
M4

Plots of theoretical and empirical modells

Theoretical probabilities

The overall final probabilites and probabilities as a function of \(\theta\)

risk low med high
4.6 21.5 34.6 39.1

Items and cutoffs
