r(2000) with all numeric observations

[jose simi]

Hi i am trying to run a time series analysis in Stata 12.0 but the r(2000) is the only thing get!!

i searched in many forums and nothing is helping.

my variable is not a string and has no missing values here it is


. describe(p1)

storage display value
variable name type format label variable label
-----------------------------------------------------------------------------------------
p1 double %10.0g p1

. sum(p1)

Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
p1 | 145 5.165996 .4178336 4.531062 6.009164

. count if missing(p1)
0

. count if !missing(p1)
145


. destring p1, replace
p1 already numeric; no replace

. tsset data1, daily
time variable: data1, Dec-94 to Dec-06, but with gaps
delta: 1 day

. dfuller p1, lags(1)
no observations
r(2000);

I guess the problem is the original data from excel, all the Stata examples work fine, only my data does not.
and i do not know the difference between count missing and !missing.

Thanks to anyone who help.
