Dear all,
Thank Prof. Baum for the reply. I will try your suggestion.
I was able to get around the problem with some experiments. What I found is
that EViews recorded date as "01 Dec 90" and STATA reads that as the number
of days elasped from 01/01/1960. Even when you format it, the internal date
is the same, and when you -tsset- to monthly, there are gaps between dates.
What you need to do is to convert to the number of months from Jan/1960, not
the number of days.
Here is what I did by point-and-click:
1/ Use -format date %dm/cy- to display "date" as "Dec/1990" then copy and
paste into a new_var. This will copy only the string label and the old
variable name "date" as the obs #1, so I had to delete this obs.
2/ Use -generate month = monthly(new_var, "my")- /* This will convert the
string to number of months sind Jan/60.
-tsset new_var, monthly
That will do the job, but it takes a lot of step and not as clear cut as
Eviews in handling time.
Best regards,
Ky Tran

I moved my data from Eviews to STATA and I am having difficulty in -tsset-
the data. The variable "date" imported and displayed as "01 Dec 90". I use
.format date %dm/y
and the variable is now displayed as "Dec/90". However, when I -tsset- the
data using
.tsset date, monthly
STATA gives the message:
. tsset date, monthly
time variable: date, 2901m1 to 3159m9, but with gaps
But there is no gap in my monthly series. I could not do -dfuller- on the
dataset, and the message is:
. dfuller m1
no observations
r(2000);
per my posting last week, suggest that you -findit tsmktim-
Kit
I read the help online and the time series manual but couldn't find any
solution.
