The tobit models, Also called a censored regression models (Tutorial Tobit Eviews 9) (Guide Tobit Eviews 9) (Regression Tobit Eview 9), is designed to estimate the linear relationships between variables when there is either left- or right-censoring in the dependent variable also known as censoring from below and above, respectively). Censoring from above takes place when cases with a value at or above some threshold, all take on the value of that threshold, so that the true value MIGHT be equal to the threshold, but it MIGHT Also be higher. In the case of censoring from below, Reviews those values that fall at or below some threshold are censored. This manual or tutorial or Guide Regression Tobit Using Eviews 9 (Tutorial Tobit Eviews 9)
