Greetings.
Please pardon this more general statistical question, although it has a
STATA component.
I'm reading a paper in the soc literature by Portes & MacLeod (
"Educating the Second Generation: Determinants of Academic Achievement
among Children of Immigrants in the United States"
Journal of Ethnic and Migration Studies, 1999).
Before conducting multivariate analyses, the authors present measures
of bivariate associations (which economists rarely do). They compare
mean values of various predictors (e.g., English ability) by national
origin groups and show eta values for each variable. Eta ranges from
0.04 to 0.41.
1. What is the "coefficient of strength of association"? What exactly
does eta measure?
2. They state "all intergroup differences (except sex) are significant
at the 0.001 level." Does this mean all possible intergroup differences
(C6,2)? Group differences from the sample mean?
3. How is eta calculated in STATA?
Thanks. Appreciate your help.
