Models

Text Description is below the image.
  • Problem with tobit model
    • Assumption: truncated normal distribution
    • A deviation to the assumption will lead to significant bias
  • Using binary PSIs as dependent variables
    • Generalized Estimating Equations (GEE) Logit Model (predict odds of bad performance)
    • Log(pit/1-pit)= b0 + b1CAHit+ ΣbnXit + ΣbmZt + eit
    • The variance function is pit(1-pit)
    • We assume the within-subject association among repeated measures is a first-order autoregressive correlation pattern
