Logistic Regression

Logistic Regression in R with Single-Trial Data

The examples in this post is taken from a class I took at the University of Missouri. These examples are originally provided in SAS and I translated them to R. The relationship between countries’ credit ratings and the volatility of the countries’ stock markets was examined in the Journal of Portfolio Management (Spring 1996). Our interest lies in whether volatility (standard deviation of stock returns) and credit rating (in percent) can be used to classify a country into one of the two market types (developed or emerging).
