summing multiple series

Hello all, I have a question that seems very simple in nature, but I can't seem to find the right command despite my search efforts. At the moment I have a number of forecasts generated in a loop and weighted them according some function of the MSE (not important). I now want to create a new series ...

Re: Phillips-Perron unit root test with prewhitening

I noticed this option is available for FMOLS estimation of a cointegrating regression, but not for the PP-test.

In my humble opinion, this would be a valuable addition to eviews in a future update.

Greetings,

Etienne

Phillips-Perron unit root test with prewhitening

Hello, I am trying to perform a PP-test for unit roots on three economic time series (M1,M2,GNP). Following the literature on bandwidth selection (e.g. Cheung and Lai, 1997), I want to perform the PP-test with the use of a prewithened QS-kernel and Andrews bandwidth, where the prewhitening is based ...

Re: one step ahead forecasts with expanding window

Thanks for the fast response again. I understand what you mean, but do you perhaps know of any clever way to get the forecasts in a series? Generating 11*550 new variables might not be the most efficient way to go about this :|

Re: one step ahead forecasts with expanding window

OK, one more question. I hope somebody will read this so I do not need to open a new topic, as the question is kind of related to the previous one. I am again trying to produce a series of recursive (expanding window) one step ahead forecasts. This time I am using a VAR model with endogenous and exo...

Re: one step ahead forecasts with expanding window

My apologies, I used the wrong loop size before and edited this in my post, which seems to have solved the problem indeed. :oops:

Thanks for the verification!

one step ahead forecasts with expanding window

Hello, I am new to Eviews and have never programmed before, so my apologies for the ignorance that will shine through in the code I am about to post below. My problem is the following. I have a sample consisting of 1757 observation and I want to perform dynamic one step ahead forecasting on the last...
