st: RE: : "year not regularly spaced" and newey
I think Newey is only suitable for time series.
Newey2 is the user-written extension for panel data.
may be someone can help me with the following (hopefully small and easy)
I have a panel with 26 panel units and a time variable from 1 - 19 (
1984 to 2001, respectively).
I have tsset-ed the data and tried to run the following regression
newey logKrimrate1a ........... year1986 - year1997 if year > 1985 &
year < 1999 , lag(1)
which resulted in the message:
"year is not regularly spaced"
There are some missing values in my dataset, but not for the time period
under investigation (1986 - 1998). year1986 - year1997 are time dummies.
This message occurs independently of if I use a year variable (1984 -
2001) or a time period variable running from 1 to 19.
If I use newey2 ( instead of newey), however, a regression result is
So my question is, why does this message above occur ????
Or is 'newey' inappropriate for panel data ?
