Hi Samiya,<br>
<br>
So apparently the function doesn't recognize any model for which to calculate some weights.<br>
In other words, all your models are considered to have a score of 0 (or rather NA as I'd rather think).<br>
<br>
I guess it might come from the 'weight.method' that you choose, did you run it in Models ?<br>
Else, can you check the values in 4th column of the Evaluation.results of your method to see<br>
what you have there.<br>

Hi Wilfried,<br>
<br>
Thanks so much for the help. I did manage to fix the Projection<br>
problem I was having(now I have a new projection problem)<br>
<br>
And now I am also having problems with the actual<br>
Ensemble Forecasting. This is the error I am getting:<br>
<br>
Ensemble.Forecasting(Proj.name= "area", weight.method='Roc', PCA.median=T,<br>
+ binary=T, bin.method='Roc', Test=F, decay=1.6, repetition.models=T)<br>
Sp1<br>
Error in rep(1, sum(wk != 0)) : invalid 'times' argument<br>
<br>
Is it because GBM is included again when it says repetition.models=T?<br>
<br>
I tried putting only the ones that are tru, but I got errors for that as well.<br>
<br>
What does the line mean - Error in rep(1, sum(wk != 0)) : invalid<br>
'times' argument?<br>
<br>
Thanks again for any help.<br>
<br>
Best wishes,<br>
Samiya<br>
