The other reason rests on missing values. WebBeta, Tobit regression and ML can be used to capture the key features of the phenomena under analysis.

WebNon-constant variance across observations (heteroskedasticity) results in the maximum likelihood estimators of tobit and probit model parameters being inconsistent. Some of the available tests for constant variance across observations (homoskedasticity) are discussed and examined in a small Monte Carlo experiment. WebThe “correct” model here is likely the Tobit model. We have an work in progress branch “tobit-model” on github, if anyone is interested in censored regression models.

Actually, both Tobit and the Heckman procedure aim to address censoring (sample selection). So you should not look at censoring and sample selection as separate concepts. The problem with Tobit is that it assumes that the same equation governs the selection (censoring) process and the continuous process. family zone setupWebTobit, modello Modello per la media condizionata di una variabile Y dato un vettore di regressori X.
