unbalanced panel "xthreg"

[sedki zn]

Dear all

i hope you are doing good

i have got a problem while balancing my panel data to run a threshold model using xthreg

using a 2008-2019 period, as mentioned, i get the following errors messages

when i use only xtbalance; range (year1 yearN), the command works but not xthreg. unfortunately, when i add miss(_all) option i get the the problem mentioned above ( i am wondering why because already 2009 is greater than the smallest year in sample (2008)

i would appreciate your help

Best regards
SEDKI

Dear sedki, Firstly, you CANNOT use the dependent variable RD as the threshold variable. 2. Please try

xtbalance, range(2009 2018) miss(RD SIZE MTB AG ceo_tn div INDEXfcp)
