search for: discrimiation

I used the "lda" function in the MASS library of S-Plus (R) to do a linear discriminant analysis, and got the linear coefficients, say b1 and b2 for the 2 predictors x1 and x2. I have trouble to calculate the discrimiant scores for each observation, I used 3 ways to try to repeat the scores returned by the "predict" function in S-Plus: 1. b1*x1+b2*x2 2. b1*(x1-mean of

Hi. I asked a question about lda() and got some answers. However, one question remains (which is not independent of the earlier ones): What output does lda() produce which I can use to compute the posteriors? I know predict(lda())$posterior will give me precisely the posteriors, but suppose I'd like to compute them myself, outside of R. So far, I have not been able to use

...is .ogg, to to magic detection on the initial OggS, and that the mime-type is application/x-ogg. We reevaluated the extension issue (the answer was no) and the mime-type issue (we were swayed) and decided we'd recommend multiple mimetypes when we have the video codec working, and add efficient discrimiation to the requirements for the toc/metadata substream we'd always planned on. None of this is a pressing issue; the useability arguments are moot until we actually have both audio and video data. That's the story so far. Now, what are our options for implementation? I'd proposed we com...
