I am trying to build a model where I want to measure the accuracy with which supervisors can predict the outcome of test taker's scores. For example, supervisors rate test taker's subjectively before taking a test based on a short interview. After the completion of the test, test results will be compared with the prior assessment.
Would a simple regression model with the subjective test score as the independent variable and the subjective prior assessment score as the independent variable make sense? I see that there might be a problem with cross-correlation but I'm having trouble understanding how. How could an appropriate model look like?
Thanks in advance.
