This semester I wrote my thesis on the determinants of municipal bond ratings. I created my own econometric model which may be used to forecast changes in future bond ratings. My math talk will discuss the regression techniques which I used in this model and analysis. I will introduce techniques such as ordinary least squares and probit analysis. I will also focus on the importance which certain assumptions play in applying each of these estimation methods. The main assumption I will discuss is that of homoskedastic residuals.
