Writing a text message to the output file

Hi I want to write a text message to the output file : output(t) c:\out.txt text message ls x1 c x2 Could you please help? I tried to use logmsg and logsave to the above output file. However, only regression result is written to the output file, but not the text message. Thank you very much, Horward

Re: Seemingly Unrelated Regressions and robust covariance matrix

yes. all I see in the help manual are running sur interactively. I have many equations and must write a program.
I am looking for a sample program in the manual illustrating the codes for specifying a simple two equation system of sur. thank you very much.

Re: Seemingly Unrelated Regressions and robust covariance matrix

Hi,

I am trying to estimate a two equation SUR system sys1 as follows

y c1 x1
z c2 x2

how do I specify the system and estimate sys1.sur? I can't find a sample program in the manual to run sur.

thank you so much, Howard

Re: how to change axis scale?

Hi, Gareth, thank you so much. My question wasn't written clearly. I have 24 observations. A default plot will label the horizontal axis as 1,2,3,...24. I want to change the label to 0,1,2,...23. How to specify the command? thanks, Howard

Re: how to change axis value?

Hi, I want to do a plot with 24 observations. A default plot labels the horizontal axis as 2,4,6,...24 (obs.1-24). I want to change the horizontal axis to 1,3,5,...23 with the same 24 observations. How do I specify the command in my program? Thanks, Howard

Re: PANEL DATA

I want to create 3 continuous series: y1 contains only x1 (when h1=1), y2 contains only x1 (when h1=2)...the sample size for each series will be 1/3 of whole sample

two-sample equality tests

Hi, I have a series x and a classification variable 'hour' with value 1 or 2. How to write a program to test the difference between the mean, median and standard deviation for the two samples. I understand that two-sample tests can be done interactively but I have many series. How to write a program...

Re: do freeze not working

Thanks a lot for your reply. Attached is the output from x.statby. I want to save the 'mean' into a series for plot. However, @mean or @meansby(x, @hour) cannot retrieve the 'mean' below. I couldn't find x.statby from the manual. Any suggestions? Thank you.
