Prediction for Bases of Influenza Virus A /HA Protein Sequence

Abstract:

Based on the chaos game representation walk model and the integer-order difference,the purpose of this paper is prediction for bases of influenza virus A /HA protein sequence.For the 71 selected protein sequences with high homology from 1943 to 2013,we use ARIMA(p,d,q) model to fit and predict its former 20 positions,almost all the raw data are in the forecast region except a few,showing that this model is more reasonable,and prediction of the effect is very good.It’s important significance for the study and prediction of influenza virus.
