A variety of qualitative dependent variable models are surveyed with attention focused on the computational aspects of their analysis. The models covered include single equation dichotomous models; single equation polychotomous models with unordered, ordered, and sequential variables; and...

A preliminary investigation of two specification error problems in truncated dependent variable models is reported. It is shown that heteroscedasticity in a tobit model results in biased estimates when the model is misspecified. This differs from the OLS model where estimates are still...

The paper explains how the Almon polynominal lag specification can be made stochastic in two different ways - one suggested by Shiller and another following the lines of Lindley and Smith. It is shown that both the estimators can be considered as modified ridge estimators. The paper then...

[eng] Estimation of Short Run and Long Run Elasticities of Energy Demand from Panel Data Using Shrinkage . Estimators by Hongyi Li, G.S. Maddala and Robert P. Trost . In the analysis of panel data, there are, broadly speaking, three approaches: to present separate estimates of the parameters in...
