In Part 2 we examined in detail the consequences that ensue when one or more of the assumptions are not satisfied and what can be done about them. In Part 3 we study some selected but commonly encountered econometric techniques. In particular, we discuss these topics: (1) nonlinear-in-the-parameter regression models, (2) qualitative response regression models, (3) panel data regression models, and (4) dynamic econometric models. In Chapter 14, we consider models that are intrinsically nonlinear in the parameters. With the ready availability of software packages, it is no longer a big challenge to estimate such models. Although the underlying mathematics may elude some readers, the basic ideas of nonlinear-in-the-parameter regression models can be explained intuitively. With suitable examples, this chapter shows how such models are estimated and interpreted. In Chapter 15, we consider regression models in which the dependent variable is qualitative in nature. This chapter therefore complements Chapter 9, where we discussed models in which the explanatory variables were qualitative in nature. The basic thrust of this chapter is on developing models in which the regressand is of the yes or no type. Since ordinary least squares (OLS) poses several problems in estimating such models, several alternatives have been developed. In this chapter we consider two such alternatives, namely, the logit model and the probit model. This chapter also discusses several variants of the qualitative response models, such as the Tobit model and the Poisson regression model. Several extensions of the qualitative response models are also briefly discussed, such as the ordered probit, ordered logit, and multinomial logit. In Chapter 16 we discuss panel data regression models. Such models combine .
