Abstract: | Given a sequence of random variables taking values in {?v,…,0,…,+u}, let's define the local score of the sequence by Hn=max1?i?j?n(∑k=ijXk). The local score is used to analyze biological sequences pointing out regions of the sequences with interesting biological properties. In order to separate randomly events from really interesting segments, we establish here the distribution of the local score of Hn when the sequence is a Markov chain of order 1.
