Models

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(p_it/1-p_it)= b₀ + b₁CAH_it+ Σb_nX_it + Σb_mZ_t + e_it
- The variance function is p_it(1-p_it)
- We assume the within-subject association among repeated measures is a first-order autoregressive correlation pattern
