Dear Dr. Muthen, I applied a random items effect IRT model to the PISA data and saved all factor scores. I understand the S1 Mean is the value for group-specific discrimination parameter for item#1. What does the B_Y1 Mean stand for? Thank you! SW |

B_Y1 is the random intercept for Y1, that is, the between-level component. |
