Hello all, I am facing a problem, hope anyone could help me out: For my training set of speech frames, I calculated 2 continuous features say x1, and x2 each of which lies in a range of bins .
I have also calculated the conditional probability distribution P(x1|x2) for all the training data set were where P(i|j) is the conditional probability that x1 is in the i-th x1-bin, given that x2 lies in the j-th x2-bin.
Now I am required to build the cumulative density function P(x1>threshold t|x2), for a certain predefined threshold t(a threshold chosen from the range of values of x1).
I hope anyone can help me out, and give me any hint on how to build this cumulative density function using Matlab... I apologise if my questions seem a bit naive but its my first time to try to use Matlab in Statistical concepts. Thanks alot in advance
