Hi,
I used fscmrmr() on a dataset of 100 observations by 1000 features. The top 100 features have scores 0 where as the remaining features have some scores > 0. Is this normal?
Assuming the idx and scores below were already ranked.
[idx,scores] = fscmrmr(X,Y);
Many thanks

Hi,
load ionosphere
[idx,scores] = fscmrmr(X,Y);
bar(scores(idx))
xlabel('Predictor rank')
ylabel('Predictor importance score')
One important thing to note is that idx and scores are in sorted order.
scores
idx
Hope this helps!
