Traj Command Error

[YongJei Lee]

I am using MP 14 ver. and was able to use traj. command until a couple of months ago. Now I see the following message and even can't reinstall the traj. plug-in.
Please advise me.

. traj, multgroups(3) var1(D*) indep1(T*) model1(zip) order1(0 3 3) var2(S*) indep2(T*) model2(zip) order2(0 3 3) var3(L*) indep3(T*) model3(zip) order3

Try changing http to https in your net from command.

Have the same problem, unfortunately.

Is this problem due to the old ver. of Stata 14 MP?

[Nick Cox]

Stata improved download from https sites on 22 September 2015. If your copy of Stata 14 is older than this you need to update.

But if you used traj recently aren't the files already on your machine?

It worked well recently. However, it doesn’t work and I can’t reinstall the traj. Plug-in.

Problem resolved following the instructions as below:
1. Update State 14 manually from the https://www.stata.com/support/updates/stata14.html
2. Go to https://www.andrew.cmu.edu/user/bjones/
and use the following link to install traj.

. net install traj
