Dear all,

The dependent variable is a count of the number of page views.

inc50per = income in the 2nd lowest quartile inc75per = income in the 2nd highest quartile inchigh25 = income in the highest quartile of earners in the population

I run the model separately for men and the code I use looks as follows:

------------------------------------------------------------------------------------

-------------------+----------------------------------------------------------------

inclow25#conf_inc | 1 1 | 0 (empty)

inc50per#conf_inc |

inc75per#conf_inc |

inchigh25#conf_inc | 1 1 | 0 (omitted)

-------------------+----------------------------------------------------------------

-------------------+----------------------------------------------------------------
