*************************************************************************
* Problem set 9, logistic regression, with binary outcome y2;          **
* Predictors are x1 (dichotomous), x2, x3, and x4, where x2, x3        **
* and x4 are measured on 9-point scales.                               ** 
* There are two additional dependent variableS in the file,            **
* y3 has three categories, and y4 has four categories.                 **
* Data simulated by Aaron Taylor;                                      ** 
* Note that y2, y3, and y4 are based on the same continuous variable,  **  
* just using different numbers of categories in coarse categorization. **
