"Felix Hebeler" wrote in message ... I see. Tried it again with 0.5% nonzero elements, and indeed A=randn(1000,1000)+5; B=sprandn(1000,1000,0.05); This is indeed a 5% sparsity. But your original example was not 10%, but 30% non-zero. B=sprandn(1000,1000,0.3); This is far too full to see much benefit. John Yes, I think a full matrix using NaNs might be more efficient for low sparsities. 10% nzes using.http://www.newsisfree.com/iclick/i,289949450,15637,o/ Re: linear or non-linear pattern in Logistic Regression- (Found June 19, 2008 ) Li Xin wrote: I have a question on Logistic regression functionDoes it work only for the problem with the linear relationship between the predictors and the logit function Logistic regression is defined as modelling the logit of the response probability as a linear function of the predictors, and that's what GLMFIT does.
