Tobit Analysis
In defining Tobit, James Tobin (1958) quoted a passage about how nothing could not be less than nothing. Tobit permits analyzing dependent variables with zero as their lowest value and that are from CENSORED DATA, and it avoids violating ORDINARY LEAST SQUARES' (OLS) continuity and unboundedness assumptions about DEPENDENT VARIABLES. OLS can produce negative ...
