Re: Passing series names to alpha

I wrote a program that reads an Excel file, importing time series to a work file (NAMES and values). How I can have internal access to the names (strings) of the series of the work file ? I want to manipulate these strings in alpha variables, constructing in an automatic way, long strings with thes...

The forum search feature needs a bit of attention. I entered the term "bar" (without the quotes) and nothing was found, despite there being an entry with "bar" in both the title and body.

Re: why do I get negative Rsquared in SURE?

Dear all, I want to estimate a system of equations simaltaneously,I am running a the system using SURE (seemingly unrelated regression). I usually get negative R squared for at least one or two of the equations. Why would this happen? and if this is possible how can I comment on the model. This als...

Re: Interpolation methods

Does anyone know more details regarding the cubic spline interpolation function on eviews? Is it appropriate for obtaining smooth yield curves? Thanks. Unless you are mandated to use a cubic spline, I recommend you try a Nelson-Siegel curve. It is easily fit by a regression and has better propertie...

Re: Double Booststrap

I am trying to run a double bootstrap program, which is very computationally intensive. It involves about one million iterations. Is there any way to boost Eview's allocation of memory to speed up how fast the program runs? My first attempt took nearly three weeks before my computer crashed. A newe...

copy table title

It is mildly odd that if you give a table a title and then copy/formatted the table to the clipboard, that the title doesn't come along

Re: Direct Forecasting

Hello colleagues, i want to forecast a sample not by iteration, but direct. This means for example, that my AR model looks like this: y(5) c y(-1) y(-2), if the forecast horizon is 5. Because Eviews is not able to forecast it by the commands "fit" or "forecast", I have to progra...

Re: N-Step ahead Out-of-Sample-Forecasts

Possibly it is. But how can I perform a dynamic forecast without using state space equations (since I am not familiar with it)? If I apply the forecast command there is no option to chose a value for n. Hence, I just perform a one-step ahead forecast before including the next observation, reestimat...

Re: Pool estimation

i am confused. to put it in perspective lets say i have three countries 2 of them are open for competition and the other not. does the latter not imply that the dummy variable for the two will be one and the other zero. Just look at your data. If for every observation either D1=1 and D2=0 or D1=0 a...
