The tobit model, also called a censored regression model, is designed to estimate linear relationships between variables when there is either left or rightcensoring in the dependent variable (also known as censoring from below and above, respectively).The tobit model, also called a censored regression model, is designed to estimate linear relationships between variables when there is either left or rightcensoring in the dependent variable (also known as censoring from below and above, respectively). tobit regression model pdf

The censored regression model is a generalisation of the standard Tobit model. The dependent variable can be either leftcensored, rightcensored, or both leftcensored and rightcensored,
