Dear Colleagues For several years, I have been thinking about cointegration regression involving stationary variables as explanatory variables. I am looking for comments on whether the following procedure is appropriate. I would be very grateful if you could advise me. Setting: - y(t)=a + b1*x1(t) +...

Dear Tom,

Sorry, I guessed wrong.
One problem still remains.
Why do I get zero variance for SIGMA?

Any comments are welcome.

Thank you for your cooperation.

Dear Tom, Thank you so much for your advice. As shown in the attached rpf, I got a good estimation. By the way, in UG-383 in Users Guide 810, we find, *************************************************** Note that you still need a dependent variable series, though its only real purpose is to show whi...

Dear Tom and colleagues, Could you help me? I would like to do CVM (contingent valuation method) analysis. So, following UG-383 in Users Guide 810 and ver3p217.rpf, I perform interval estimation using LDV instruction. However, I can't obtain good results. Could you tell me why? I attach the rpf file...

Dear Tom, I am now using CATS2.06 and got an error message of "the chosen normalization invalidates calculation of the "standard errors" for beta" like the post above. After running the attached code, you will see the dialog for row-wise normalization of beta. Since I want to nor...

Dear Tom,

Thank you so much for your kind suggestion.
I will see the integral.
As soon as I get something meaningful, we will get back to you.

Dear Tom, Thank you so much for your comments on December 19, 2017. I am still working on this topic. This time, I attach my code. My question is simple, but let me first explain what I am doing. On this code: The attached is a code to replicate Aizenman et al (2000) which investigates a relationshi...

Dear Tom,

By reading Reference Manual on "unmake," I could make the scatter as I hope.
Thank you so much for your kind assistance!

Dear Tom, I am confused again. I want to make a scatter with X and Y. dec vec X(100) dec vec Y(100) (For example) do i = 1, 100 compute X = X +1 compute Y = 2Y +3 end do scatter # X Y How can I transform X and Y into SERIES? (Where should I read in manuals?) Thanking in advance for your trouble.

Dear Tom,

I'm terribly sorry to bother you over and over again.

Could you teach me if it is possible to maximize a expected value like below ?

max log(C1) + S log(C2+e) f(e) de
s.t. C1 + 0.9*C2 = 1 where e ~ uniform(-1.0, 1.0).

( "S" above means integral here.)

Yours Sincerely.

Dear Tom,

It seems that I need a bit more time to use FIND well....
Anyway, thank you so much for your kind assistance!

Sincerely,

Dear Tom, Thank you for your kind suggestion yesterday. Unfortunately, I face the next priblem. I am now computeing a simple optimal borrowing problem of a governmnet with 2 period, CES utirity, like: compute Y1=1.0, Y2=1.0 nonlin B find max (1/1-R)*c1^(1-R)+(1/(1+r))*(1/1-R)*c2^(1-R) compute T_1 = ...

Dear Tom,

Thanks to your warm kindness, I finally obtain the solution.
My collections are as follows.

(1) I simply add
compute C1 = 1.0
etc..

(2) I modify

compute gamma_1 = (lamda/2)*(t1**2)

to

compute gamma_2 = (lamda/2)*(t2^2.0)

Again, I deeply appreciate your kindness.

Sincerely,

Thank you for your reply.

>Because you never defined C1 (or C2). That's what the message is telling you.

I wrote:

compute c2 = (1-xi_2-gamma_2)*Y2

at the end of Find-End loop.
Do you mean the order of my code is wrong?
Or, simply I should add,

compute C1 = 0.0
compute C2 = 0.0

before FIND ?

Dear Tom, Thank you so much for your SO prompt reply. Please ignore my previous post. I think I am going to reach the goal. This is my code. compute Y0 = 1.0 compute Y1 = Y0 compute Y2 = Y0 compute delta = 0.3 compute R = 1.2 compute G = 0.2 compute rho = 0.1 compute alpha = 0.5 nonlin B find root (...
