Select by clicking on "Conditional Probabilities" or from the Graphs menu. Conditional probabilities of observing adjacent categories. These are a series of Rasch dichotomous ogives. The intercepts with 0.5 probability are the Rasch-Andrich thresholds. They can be disordered relative to the latent variable.
Buttons are described in Graph window.
Polytomous RP50 values are the points where the ogives cross the 0.5 line. Click on "Absolute x-axis" for values relative to the latent variable. "Copy data to clipboard", then paste into Excel to see the numerical value.
Polytomous RP67 values are the points where the ogives cross the invisible 0.67 line. Click on "Absolute x-axis" for values relative to the latent variable. "Copy data to clipboard", then paste into Excel to see the numerical value.
