Re: near singular matrix error

If you have two variables with identical values for every given observation, then that's the problem. After all, if the two are always the same how can the computer separate out their effects? Ok. That shouldn't be the case for any of the variables. They will share the same values for some observat...

Re: near singular matrix error

No. Setting a dummy variable to zero is not removing it. Fair :) I have attempted many different functional forms including dropping several of the variables altogether (not just dropping observations), but I still receive the same near singular matrix error, if I have a second dummy variable along...

Re: near singular matrix error

How did you drop dummies?
I picked one observation set for each of the period/time variables and made it a 0
for instance:
smpl @all
series moy = @month 'generate moy series
smpl if @month = @2
series moy = 0 'drop all february observations by setting to 0

would this work?

near singular matrix error

Hi all! I'm attempting to create a forecast of expected values to compare to actuals from a post-treatment period. However, I'm receiving a near singular matrix error. I'm almost certain this is caused by all the dummy variables I'm using (dom = day of month, moy = month of year, dow = day of week, ...

Interpolation while making adjustments in model object

Good afternoon! I'm attempting to use interpolation to make some adjustments to a forecasted series in the model object. It's been a while since I've used it, but I recall being able to simply enter a value in the first period of adjustments, a different value in the last period, and use the @ symbo...

Tree Regression Model

Good afternoon!
Does eviews have a package to run tree regression models programmatically?
Thanks!

Re: EIA API connection

Thank you so much. That is very helpful. I have to provide admin creds (not my standard credentials) locally on my machine to run the updates and register the components, so perhaps this is indeed the issue.

Re: EIA API connection

I did, but they all disappeared. I'm now routinely prompted with the "add registry" when I start eviews. I add them. They do not appear. I'd like to add an EIA connection, but I can't get it to show up in the registry under database types. In other words, the only database types that appea...

Re: EIA API connection

This worked, but about a week later I lost access to most of the registered databases. I ran regcomponent, and I'm prompted with a dialogue box saying everything was registered successfully...but nonetheless, the databases are not appearing in the database registry....any thoughts? Thanks! eviews.png

Good morning! I'm trying to determine capture the right most character from a temporary string, that is a list of the members of a group. However, the code either crashes with a syntax error if I put brackets around the code name as below group g_max hsddcus_* %max = g_max.@members %max = @replace(%...

Re: How to save a graph to use as a template

Thanks, I was looking through the programming guide and couldn't seem to find it. Could you please provide an example, or incorporate into the text below?

Code: Select all

graph mgrus_0.line g_us_0
where g_us_0 is a group.

Thanks!

I figured out that using the maxsar and maxsma options was slowing it down, and producing less accurate results. Problem solved! A follow up question: I can't seem to get the command to product the forecast comparison graphs in the loop. Code is below. Any help is appreciated. Thanks! for %x CEN NED...

Re: store autoarima in model object

I was able to figure out how to create an equation in the autoarima code, so this is solved. I did notice that eviews tends to run much slower using the autoarima function. Is this typical? It's chewing up a fair amount of my cpu/ram (58% and 68%, respectively). Is there a way I could code the equat...
