Numerical series describing the length of coding sequence (CDS) of different bacterial genomes have been analyzed in a systematic manner. The differences and also the similarities shown by two investigated bacteria have been found and discussed. The statistical tool used in our study was the high order autoregressive model (ARp) which proves to be suitable to describe in a simple way, the succession of length in the bacterial genome. The main result of the paper is that the succession of coding sequences in the bacterial genome are short-range correlated.
Key words: bacterial genome, coding sequences, autoregressive model, short-range correlation.
