minimum of constrained nonlinear multivariable function
Hi,
Is there an alternative to fmincon(matlab) in EViews? I couldnt find anything other than optimize function. I use EViews 11.

Re: Constrained least square and optimization
is this the case with EViews 11 as well?

Re: State Space modelling
you can also try adding a covariance matrix using @vprior

estimating states from EVIEWS 11
Hi, I got my model converged. However, when I forecast the state variables, I see that it has same values across periods. What can be the reason for this? Any ideas? Included observations: 148 Convergence achieved after 20 iterations Coefficient covariance computed using outer product of gradients C...

Re: regressors with fixed coefficients versus recursive coefficients
For instance, if my equation is as follows: Can you please specify which component is part of fixed and which is part of recursive? Xt = b1.Xt-1 + (1-b1).(( Xt-2 + Xt-3 + Xt-4)/3) + b2.Yt-1 – SV1.Y[*]t-1 Here I will put Xt in the dependent variable with AR =1 , but for the rest of the variables, can...

regressors with fixed coefficients versus recursive coefficients
Hi, Can anyone please throw some light on the two options - regressors with fixed coefficients versus recursive coefficients available in state space modelling within EViews? some examples on how to classify your variables into regressors with fixed coefficients and recursive coefficients. Thanks in...

Adjusted Sample Changing from one system to another
Hi, How is the adjusted sample determined in EViews when I run a stepwise regression? I included the same set of variables in 2 different systems (computers)- using the selection method as forward and asked the system to select 3 variables. When I look into the results from them, I see that the samp...

To identify groups with similar names
Hi, Is there a way that I can store the names of the groups which is saved in a similar format as a string. We can create groups with wildcard characters to match more than one series in the workfile. Similarly, I wanted to store the names of the groups which match a specific format as a string. for...

Re: Exporting to existing excel file
Hi,
Is it possible to change the sheet name via writing code in EViews? or the mode = update function is applicable only with the default name in excel?
