Hello,
I am trying to run levpet on my data. This is what I wrote
tsset firm year
set tr on
levpet lnsales, free (lnlabor) proxy (lnfuel) capital (lnk_stock) revenue i(firm) t(year) reps(50) level(95)
This is the error I get with some part of the trace preceeding it.
- capture assert int(`timevar')==`timevar'
= capture assert int(year)==year
- if _rc {
di in red "time variable must contain only integer values"
exit 451
}
- sort `panel' `timevar'
= sort firm year
- if "`panel'" != "" {
= if "firm" != "" {
- local bypfx "by `panel': "
= local bypfx "by firm: "
- }
- if `"`format'"' != "" {
= if `"%9.0g"' != "" {
- format `timevar' `format'
= format year %9.0g
- }
- tempname scdelta
- mata: _TS_p_delta("`scdelta'", "`delta'", "`timevar'")
= mata: _TS_p_delta("__00001R", "(__00001Q)", "year")
_TS_p_delta_getnumb(): 3499 strtoreal() not found
_TS_p_delta_increment(): - function returned error
_TS_p_delta(): - function returned error
<istmt>: - function returned error
-------------------------------------------------------------------------------------------- end tsset ---
}
---------------------------------------------------------------------------------------------- end xtset ---
}
else {
Can somebody help me with this. I am not very conversant with Stata. I am using Stata 10.
Thnx
Priya
