Re: Executing snippets of code quickly

True -- that's one way to do it, but not an ideal one. Having a quick way to execute a block of code (i.e. select the code and press one button) would enhance the Eviews experience tremendously.

Executing snippets of code quickly

Hi: Is there a way to select a block of code and execute it? Currently I have to copy & paste each line individually to the Command window and press 'Enter' after each one. This is extremely inefficient. In MATLAB one can simply select code and press F9 and it executes. Does Eviews have an equiv...

Re: LogL estimation - "Failure to improve Likelihood"

When I get these singularity errors, I simply re-execute the "ml" method on my LogL object without changing any of the coefficients or parameters to the ml method. Oftentimes, the MLE will subsequently converge. It takes a substantial amount of time to sit by the computer and keep re-execu...

Re: LogL estimation - "Failure to improve Likelihood"

That did not work. I originally set the convergence threshold to 1e-5 and tightened it to several values leading down to 1e-50 and still get the singular covariance error.

LogL estimation - "Failure to improve Likelihood"

Greetings: I am estimating coefficients via the LogL object in Eviews. More often than not, I get the error message: "Failure to improve Likelihood after X iterations WARNING: Singular covariance - coefficients are not unique" However, if I simply re-start the MLE estimation and not changi...

Re: Missing Values @logl

OK - Thanks. Is there a way to find out which variable is causing the problem? There should be an easier way to find the problem than sifting through all 50 regressors one-by-one.

Missing Values @logl

Greetings. I am attempting to use MLE to estimate an equation, however I am getting "missing values in @LOGL series at current coefficients at observation NNNN". Is there a way Eviews can show which variable is causing the problem? I use OLS to compute starting values for the coefficients ...

Re: Extract substituted coefficients form for an Equation

You raise some good points. I think it boils down to getting access to the equations inside a logl object. From the Model object, I can pull up the equations that I want because they have a name associated with them.
Could this kind of feature be created through an Add-In?

Re: Extract substituted coefficients form for an Equation

Thanks - perhaps I can step back and explain what I am doing as you may have a suggestion on a different route to the end goal. I am estimating two equations via the logl object. In order to get the substituted coefficient representation of the two equations, I have to "Make Model" from th...

Re: Extract substituted coefficients form for an Equation

Thank you - @subst does exactly what I was looking for.

The 2nd part of the question is how to extract a specific equation out of a model so that I can call @subst on the equation object.

Extract substituted coefficients form for an Equation

Hi All, I am trying to obtain the Substituted Coefficient representation of a numerous amount of equations. More specifically, the equations are part of different Model objects. What I have to do is manually go into each equation and copy & paste each Endogenous equation from Eviews to notepad. ...

Re: Extracting Equation from Eviews to Excel

It would be very handy for Eviews to have the ability to export to Excel the Substituted Coefficient representation of an Equation as a STRING.
