Re: How to check for existence of an URL?

Try opening it and if it fails, it doesn’t exist?

Re: Stacked lines in a time series graph with weekly obs

Unfortunately there isn't a built in way to do this (and I guess you'll be surprised to learn that nobody has requested it before!). I think I would just go with the unstacking idea. If it wasn't weekly data (i.e. there were an exact number of periods per year) you could do something easily with lag...

Re: wfselect in program does not work as expected

Slight visual only bug. The active workfile is changing, so any subsequent commands will apply to it, but the window isn't updating to reflect that visually. Note if you run the program in verbose mode, it does update visually.

We'll fix.

Re: xlsx to EViews

Drag the Excel file onto EViews. On the first tab of the Excel import dialog, specify which sheet you want. You'll have to do it once for each sheet.

You can check the length of a vector with @rows(vectorname)

Re: Rolling Regression-extracting only of the coefficients

I don't know which number you are talking about, so can't answer the first. You can use the rename command to rename ser01 etc..., but then the groups will be screwed, so you'd have to redefine the groups. I find it better to first create the series with the names I want, make a group out of those s...

Re: Rolling Regression-extracting only of the coefficients

There's always a trade off between time spent learning how to automate something and time to just do it manually... Yes, you can read the names from Excel, either as part of the data import, or separately into a table if you want (importtbl). If you bring the series in and just want to grab the name...

Re: Near Singular Matrix Error

You don't have enough data. Brazil, for example, only had 4 data points, which are non-consecutive. As soon as you take lags, you have no data.

Re: Rolling Regression-extracting only of the coefficients

When using MTOS you are assigning value from a vector into a series. To do that, you have to ensure that the number of observations you are copying is the same in both objects. For a series object the number of observations will be equal to the number of observations in the current workfile sample. ...

Seasonal dummies and trends are just X values, and work as indicated in the example.
