Dear Stata Users,
My panel data is composed of firms' bond issues over ten years. Some
firms have multiple bond issues in a given year, while other firms have
only one bond issue in a given year. I assume that observations are
independent across firms but not necessarily independent within firms.
As to my understanding, using
-reg y x, robust-
can get p-value or t-statistics robust to heteroskedasticity. But I am
not sure how to get the p-value or t-statistics that are robust to
heteroskedasticity and are also adjusted for the clustering of
observations in firms that make multiple issues? Could you please let me
know which command I should use if you know it? Thank you!
Wenxia
