Frances, I would not advise Gauss-Seidel for non linear models. Can be quite tricky, slow and diverge. You can write your model as a non linear system of equations and use one of the nonlinear solvers. See the section "Root Finding" in the task view NumericalMathematics suggesting three packages (BB, nleqslv and ktsolve). These...

...ot touched the system.fit package for quite some time, but to solve your problem the following two pointers might be helpful: 1) Recast your model in the revised form, i.e., include your identity directly into your reaction functions, if possible. 2) For solving your model, you can employ the Gau?-Seidel method (see https://en.wikipedia.org/wiki/Gauss%E2%80%93Seidel_method). This has not only the advantage of generating forecasts, in terms of your exogenous variables, but you can also compute 'dynamic ex post' forecasts. This is probably the most powerful testing for dynamic simultaneous eq...

Dear Helplist, I want to produce forecasts from a structural equation model. With the SEM package the model setup and its estimation is possible. However, I have not figured out how to obtain ex ante forecasts, i.e. applying the Gauss-Seidel algorithm to the estimated structural equations for provided values of the exogenous variables (i.e.: y_t = -inv(A)*B*x_t). Does anyone know if the there is a function for producing such forecasts via Gauss-Seidel or what other functions are supporting objects of class 'SEM' or model notat...

...this area I think this is the way to go: 1. Have a look at pluto[1] Pluto is a source to source compiler that can auto parallelize hand selected code. To check how it works I attached you an example, where it translates normal C code to OpenMP parallelized code. Compile it like this: gcc -O3 seidel.c -o seidel_sequential gcc -O3 -fopenmp -lm seidel.par.c -o seidel_parallel I tried this on a 2 Core / 4 Thread Intel processor $ time ./seidel_sequential real 0m6.923s user 0m6.890s sys 0m0.010s $ time ./seidel_parallel real 0m2.710s user 0m10.730s sys 0m0.010s One way to get this feature au...

Hello, I have estimated a simultaneous equation model (similar to Klein's model) in R using the system.fit package. I have an identity equation, along with three other equations. Do you know how to explicitly identify the identity equation in R? I am also trying to forecast the dependent variables in the simultaneous equation model, while incorporating the identity equation in the

Hi List, maybe i missed a hint on google, but i didn?t find a answer to following question: is it possible to cascade the logon scripts...? for example: there is a standard script for all client-pc?s called: netlogon.bat and in addition there is for some client-pc?s a additional script called by the %m switch in smb.conf kind regards Arno

Is there maybe a way to consolidate (At the developer level) all of the tools and methods into one concise list. samba is not really tightly integrated with the OS, Is there maybe a way to re-organise the way samba works? maybe to make it completely emulate the way it works on the windows command line? for example make everything integrated into the net command..... net use (file system

Hi! How do I configure smb.conf and/or Pam as a single sign on server if I have a LDAP server with a Kerberos as password backend through gssapi? I only see either Samba/ldap as PDC or Samba/kerberos with ads on the Internet. Not both at the same time? I've already configured samba with LDAP and Kerberos support. Everything seams to works. I also configured Samba with ads and Pam support if

Hello, I'm trying to figure out how to create a data object, and then save it with a user-defined name that is input as a command line argument. I know how to create the object and assign it the new name, however, I can't figure out how to refer to the new name for a future operation such as save(). The code below creates an object and uses assign() to give it the user supplied name

I have applied the same solution that Stephen applied for the first one, follows the pa...
