Clearing Program log

Hi,

I wanted to clear all the errors in the program log. I used the code "clearerrs" after my program. However, that is not working. Do you know what might be the reason for the same?

Re: midas regression-forecasting

was able to do that Gareth. My question is whether we can do it the other way- ie, if I have monthly values, can I forecast the dependent variable also on a monthly basis?

midas regression-forecasting

Hi,
Currently I ran a MIDAS regression with a dependent variable "y", observed at a lower frequency (quarterly) and with an independent variable "x" observed at a higher frequency (monthly). Now is it possible to forecast "y" on a monthly basis from the results?

Wanted to get a clarification regarding the option: U-MIDAS available within the MIDAS regression. Isn't this unrestricted MIDAS itself? there is no documentation regarding this option in the user guide.

Re: Rank of a matrix

I am searching for the RANK of a matrix (as in matrix algebra) that is done by Gaussian elimination-- not ranking based on ascending/ descending order. Looks like EViews doesnot offer that functionality :( developing one now!

Re: Rank of a matrix

Kindly note that I have a symmetric matrix and hence when I try to use @ranks, I'm getting an error.

Re: Last/First non-NA observation

Hi Gareth,

Is there a way that I can find the date on which the first non- na observation falls.

for instance, if I find first non-na using @first (Series)
I want to find the date associated with that particular value
I tried to use @otod as well. Can you please help me.

Thanks in advance,
Saranya
